Principal Features and Cycles of Lithuanian Calendar Customs

The Foundations and Dynamics of Lunar and Solar Calendars

The lunar calendar represents the most ancient system for tracking time in Lithuania, predicated on the meticulous observation of the phases of the moon. A lunar month initiates with the new moon (jaunatis) and concludes with the waning moon (delčia). Throughout this cycle, the moon increases in visibility for approximately two weeks and decreases for the subsequent two. While contemporary terminology distinguishes four primary phases—new moon (jaunatis), first quarter (priešpilnis), full moon (pilnatis), and waning moon (delčia)—folk tradition utilized a richer vocabulary. The waning phase was often referred to as sengalis or galadelčius, while the period of lunar invisibility was known as sanvarta, mainas, or tuštimas. Each phase maintains a nearly static appearance for three days, though the new moon phase, beginning from the first appearance of the lunar crescent, typically lasts about $7$ days. The etymology of the Lithuanian word for month, mėnuo, is directly linked to the moon (mėnulis).

Under the lunar system, a year consists of either $12$ or $13$ months. The moon completes an orbit around the Earth in $27.3$ days, but because it takes $29.5$ days to return to the same position relative to the sun, a $13^{th}$ month must be intercalated every $2$ to $3$ years to maintain alignment. Folklore frequently references three lunar phases of nine days each, leading scholars to believe that months were once comprised of three nine-day weeks, totaling $27$ days—a possible origin for the symbolic number "three nines" ($3 imes 9 = 27$). Archaeologist Marija Gimbutienė posits that lunar calendar remnants in Lithuanian customs trace back to Old European culture, where lunar phases governed the elements of water and earth, influencing tides, fish spawning, and animal migrations. This led to a lunar cult; the moon was addressed as a deity (dievaitis), greeted with prayers upon its new appearance, and represented in archaic amulets, roofing poles (stogastulpiai), and traditional ornaments. Today, lunar influence persists in determining the date of Easter and associated movable feasts, as well as in the traditions of Kūčios and Pusiaužiemis.

The solar calendar serves as the foundation for the modern chronological system, consisting of $365-366$ days, $12$ months, and $7$-day weeks. In Baltic tradition, the sun was worshipped as a female deity, often called "Mother Sun" (saulė motulė) in folklore. Archaeological evidence from the Neolithic period includes amber amulets featuring solar symbolism, which also appears on spindles, clothes-beaters, pottery, and musical instruments. The sun is often represented as a cross within a circle. The most significant solar holidays mark the solstices (solstitium), occurring when the sun reaches its highest (summer) or lowest (winter) point on the ecliptic. Interestingly, traditional celebrations lag approximately $2-3$ days behind astronomical dates: midsummer (Rasos or Joninės) is celebrated on June $23$ despite the astronomical solstice occurring on June $21$, and Christmas is celebrated on December $25$ despite the solstice falling on December $22$. Solar equinoxes are also vital; the spring equinox (astronomically March $19-21$) aligns with Stork Day (Gandrinės) on March $25$, and the autumn equinox (astronomically September $22-23$) aligns with Dagotuvės or St. Michael’s Day on September $29$.

The Evolution of the Julian and Gregorian Calendars

The Julian calendar was established in the Roman Empire by the Egyptian astronomer and mathematician Sosigenes at the behest of Julius Caesar, entering into force on January $1$, $46$ BCE. It popularized the division of the year into $12$ months and weeks into $7$ days. Before this, diverse Roman peoples calculated years from the "creation of the world" or other major historical events. The Julian year averages $365.25$ days, with three common years of $365$ days followed by a leap year of $366$ days (where the year is divisible by $4$). The Christian Church officially adopted this system in $325$ CE. However, because the Julian year is $11$ minutes and $15$ seconds longer than the astronomical year, dates drifted forward over centuries: a $7.8$ day shift occurred over $1000$ years, growing to $10$ days by $1700$, $12$ days by $1900$, and reaching $13$ days currently.

To correct this discrepancy, Pope Gregory XIII issued a bull in $1582$ introducing the Gregorian calendar. At that time, the equinox had shifted from March $21$ to March $11$, threatening the timing of Easter. The Gregorian system revised the leap year rule: century years are only leap years if they are divisible by $400$. This reduces the error to just $1$ day every $3300$ years. Lithuania was an early adopter, implementing the Gregorian calendar in early $1584$ (though Prussian-ruled Lithuania Minor followed in $1610$). After Lithuania was annexed by the Russian Empire, the Julian calendar was forcibly reinstated on January $1$, $1800$, except in the Užnemunė region. The Gregorian calendar was finally restored across all of Lithuania on November $15$, $1915$ (which was November $28$ in the Julian style). Notably, while Russia adopted the Gregorian system after the $1917$ revolution, some Orthodox Churches (including the Moscow Patriarchate and the Serbian Orthodox Church) still adhere to the Julian calendar, celebrating Christmas on January $7$.

Concepts of the New Year and Month Etymologies

Although the Julian calendar began on January $1$, the Roman New Year was historically observed in March, the month of Mars, signifying the start of the military season. This March start persisted in Western Europe for centuries. Despite the Church attempting to move the New Year to December $25$ (the Birth of Christ) in the $6^{th}$ century, it was not until Pope Innocent's $1691$ bull that January $1$ was standardized for Catholic regions. Russia observed the New Year on March $1$ until the $15^{th}$ century, and England maintained this date until $1782$. The March-based lineage survives in Latin-derived month names used globally: September (from septimus, the "seventh"), October (octavo, "eighth"), November (nonus, "ninth"), and December (decimus, "tenth").

In contrast to most European languages where month names are Latin in origin, Lithuanian month names are indigenous and reflect the natural world and agricultural cycles. They are categorized by flora (birželis - birch, liepa - linden), birds (balandis - dove, gegužė - cuckoo, kovas - rook), natural phenomena (gruodis - frozen soil, lapkritis - leaf fall, sausis - dry, vasaris - summer-like), and agriculture (rugpjūtis - rye harvest, rugsėjis - rye sowing, spalis - flax scales). The current usage stabilized in the late $19^{th}$ to early $20^{th}$ centuries. Historically, names overlapped; for example, sausis could refer to December, vasaris to January, and balandis occasionally spanned from March to June. This overlap likely resulted from the transition between the Julian and Gregorian calendars and local variations in agricultural timing.

Movable Feasts and Liturgical Timeframes

Easter is the paramount movable feast, determined yearly by a synthesis of solar and lunar cycles: it falls on the first Sunday after the first full moon following the spring equinox (March $21$), occurring between March $23$ and April $24$. Several other holidays are calculated relative to Easter. Užgavėnės (Shrove Tuesday) takes place $47$ days before Easter (between February $5$ and March $6$). Pusiaugavėnis (Mid-Lent) occurs approximately $20$ days before Easter. Palm Sunday (Verbų sekmadienis), Maundy Thursday (Didysis ketvirtadienis), Good Friday (Didysis penktadienis), and Holy Saturday (Didysis šeštadienis) immediately precede Easter. Atvelykis (Children’s Easter) is celebrated one week later. Šeštinės (Ascension) is on the Thursday of the sixth week after Easter, Sekminės (Pentecost) on the seventh Sunday, and Devintinės (Corpus Christi) on the Thursday of the ninth week.

These movable feasts dictate agricultural and social periods. Mėsiedas refers to the meat-eating period from Christmas (December $25$) until Užgavėnės. Lent (gavėnia) begins on Ash Wednesday—the day after Užgavėnės—and lasts $46$ days until Easter. Advent, the period of preparation for Christmas, starts on St. Andrew’s Day (the fourth Sunday before Christmas), varying in length from $22$ to $27$ days. Finally, Tarpušventis denotes the $12$-day festive interval between the second day of Christmas (December $26$) and Epiphany (January $6$).

Vėlinės and the Commemoration of the Dead

Ancient Balts perceived the year as a duality of winter and summer seasons rather than four distinct quarters. The cold cycle, spanning from Vėlinės (All Souls' Day) to Easter, focused on the afterlife and the ancestral world. Vėlinės stems from the belief that the soul (vėlė) separates from the body at death and continues to interact with the living. Historically called Ilgės or Dziedai (in Eastern Lithuania), this festival in the $15^{th}-16^{th}$ centuries involved multiday rituals in October. Scholars like Jonas Basanavičius noted that commemoration once extended from St. Michael’s Day (September $29$) to St. Martin’s Day (November $11$). While the Church introduced All Saints' Day on November $1$, Lithuanian folk tradition focused on feeding the spirits.

Old accounts describe graveside feasts; Jan Długosz ($15^{th}$ century) recorded regional gatherings at cemeteries involving sacrifices to Perkūnas to strengthen the souls. Alexander Guagnini ($16^{th}$ century) described Samogitians visiting graves with milk and mead, accompanied by dancing and music. Although the Church eventually banned graveside dining, customs of leaving bread, porridge, or scattering grains survived until the $19^{th}$ century. A notable tradition was the slaughter of a ram on the eve of Vėlinės, with meat donated to beggars or used for a ritual dinner. Motiejus Valančius noted that Samogitians served spirit bowls of šiupinis and raugtienė. The house was prepared for spirits: saunas (pirtis) were heated, windows and doors opened, and sharp objects hidden to prevent accidental injury to the visiting souls. In Dainava (Dzūkija), the first spoonfuls of every dish were sacrificed to the dead, and a circular loaf of "beggar's bread" was baked specifically for the spirits.

Today, fire remains the central symbol of Vėlinės. Historically, it was believed that spirits were cold; the living lit fires—often burning old crosses and branches in large cemetery bonfires—to warm them. This tradition, known as "warming the dead's feet," persists in villages such as Margionys, Mardasavas, and Musteika. The night of Vėlinės is also associated with "wandering souls" and those who died unnatural deaths; lights were said to flicker over forgotten graves. Since the $1960s$, the ethnocultural movement has introduced a custom of singing orphan songs and folk laments at burial mounds (pilkapiai).

Halloween: Transitions and Cultural Intersections

Halloween’s origins lie in the ancient Celtic festival of Samhain (meaning "summer's end" in Celtic), which marked the transition into the cold cycle on the eve of the Celtic New Year (November $1$). It was believed the boundary between worlds thinned on October $31$, allowing spirits to visit. Druids made prophecies and lit massive bonfires. People wore costumes of animal skins or skulls to commune with or ward off spirits. Turnip lanterns with carved faces (later pumpkins in the US) were placed at thresholds. The tradition of "guising" involved youth going door-to-door performing songs or jokes in exchange for treats, fruit, or nuts, mirroring the Lithuanian Užgavėnės mummers.

Christian influence in the $9^{th}$ century turned November $1$ into All Hallows' Day, making the eve All Hallows' Eve, eventually shortened to Halloween. In the British Isles, customs like begging for "soul cakes" in exchange for prayers for the dead emerged. When Scottish and Irish immigrants arrived in the US in the mid-$19^{th}$ century, they popularized the pumpkin Jack-o'-lantern (named after the legend of Stingy Jack). By the early $20^{th}$ century, Halloween became a North American communal festival focused on the "trick or treat" phrase. Although modern Halloween is often demonized or commercialized, it shares profound roots with Vėlinės, including ritual food, fire symbolism, and the desire to navigate the relationship between the living and the dead.

Late Autumn Cusp: St. Martin and Goat Day

The end of autumn is marked by St. Martin’s Day on November $11$. In the $16^{th}-17^{th}$ centuries, this was the legal deadline for taxes and payments to farmhands, blacksmiths, and herders. For shepherds, it signaled the end of the grazing season as livestock were moved to the barn. November $12$ was celebrated as Ožio diena (Goat Day), intended to signal the arrival of winter. To summon snow, shepherds decorated a white goat, sometimes crowning it, and led it three times around a birch tree. They danced, gave speeches from stumps or buckets, and shared a final outdoor feast of scrambled eggs made from $12$ eggs. In Samogitia, a roasted goose was eaten, and its breastbone used for weather divination.

Advent Customs, Restrictions, and Markets

Advent (from Latin adventus, "coming") officially begins on the Sunday nearest to St. Andrew's Day (November $30$). Before the mid-$4^{th}$ century, it lasted seven weeks, similar to Lent. St. Andrew’s Eve is a major night for divination: cherry or plum branches are placed in water, and if they bloom by Christmas morning, a wish will come true. Marriage divinations included circling a well three times backward or sowing hemp seeds by the bed to see a future spouse in a dream. While fasting is traditional, Protestant Lithuania Minor did not strictly enforce fasts, and even allowed weddings during Advent.

Advent mythology is populated by witches (laumės), ghosts, and animals like wolves; December was historically called "Wolf Month," and offerings were sometimes given to them. Work restrictions were strict: any work involving circular motion (spinning, milling) was avoided to ensure nature's cycle remained undisturbed. People gathered in evening socials (vakarojimas) to pluck feathers or weave ropes while singing songs with archaic refrains like leliumai, aleliuma loda, or kalėda.

In Northern and Eastern Lithuania, specific Advent markets were held: Šeškaturgis (Polecat Market) for warm clothing and furs; Skaistaturgis (Bright Market) for gifts, ribbons, and hats; and Saldaturgis (Sweet Market) for food staples like honey, poppies, and cranberries. In Lithuania Minor, the "Goose Market" (Žąsų turgus) tradition was bolstered in $1934$ when the government mandated that civil servants purchase surplus geese to mitigate an economic blockade by Nazi Germany. The Advent wreath, featuring four candles, also originated in the late $19^{th}$ century in Lithuania Minor.

St. Lucia and its Disconnection from Lithuanian Tradition

St. Lucia’s Day (December $13$) is a Swedish festival of light. Historically, under the Julian calendar, this date coincided with the winter solstice. However, due to the Julian calendar's drift ($11$ minutes and $15$ seconds error annually), the solstice moved. When Sweden adopted the Gregorian calendar in $1753$, they kept the date on December $13$ but lost the solstice connection. Lithuania adopted the Gregorian calendar much earlier ($1584$), and its Christmas traditions already encompassed the archaic symbolism of light's victory, rendering the "borrowed" Swedish festival redundant in native Lithuanian culture.

Kūčios: Decoration, Preparation, and the Ritual Meal

Kūčios (Christmas Eve) follows the solar calendar and marks the solstice. Its namesake is the dish kūčia, a mixture of grains, beans, peas, poppy seeds, nuts, and honey. The holiday emphasizes reconciliation and debt settlement. Houses are decorated with straw gardens (sodai) featuring straw birds and solar symbols; this tradition was added to the UNESCO Intangible Cultural Heritage list in $2023$. A bundle of grain is placed in the corner to ensure future harvests. The Christmas tree was a late addition, mentioned by Antanas Baranauskas in $1853$ in Vainutas, and spread through Russian schools and manor houses before becoming a village staple.

On Kūčios day, spinning, sewing, and wood-chopping are forbidden. Ritual cleanliness requires a sauna bath. Hosts perform magical circular walks, circling the house or orchard three times to simulate the sun and protect the property. The table is prepared with hay under a white linen cloth—symbolizing both the spirits and the manger. The meal consists of $9$, $12$, or $13$ meatless dishes. Standard items include kūčiukai with poppy milk, oat or cranberry kisielius, herring, and mushrooms. Samogitians used crushed hemp, while Southerners (Sūduva) preferred boiled peas. A plate is left for deceased family members or those far away, and beggars are traditionally invited. The host circles the house three times, knocking and announcing himself as the "Lord God" or "Holy Spirit" before sharing the kalėdaitis (blessed wafer). Divinations follow the meal, such as pulling straws from under the tablecloth to predict life expectancy.

Christmas Celebrations and the Myth of Kalėda

Lithuanian Christmas celebrations historically lasted $3-4$ days. The first day was dedicated to the family and church. Racing home from church was common, with a belief that falling from a sled would ensure a good flax harvest. The menu centers on pork: head, sausages, hams, and even whole piglets. Goose was only popularized as a Christmas dish in the interwar period. A distinct ritual was blukio vilkimas (log dragging), where a large stump (blukis) was dragged through the village by blukvilkiai accompanied by mummers. The log gathered the year's misfortunes and was burned to symbolize the restoration of world order.

Kalėdotojai (carolers) began visits on the evening of the first day, continuing through Epiphany. Groups included regional characters like "the bear" in Lithuania Minor or "the horse-rider" (Šyvio šokdintojai) in Gražiškiai. The central figure is Senis Kalėda (Old Man Christmas), an archaic figure unrelated to Santa Claus. He wears inside-out furs and a flaxen beard, arriving from "the other land" where it rains candy and snows bagels. He is linked to the divine blacksmith Teliavelis, who forged the sun. January $6$ (Epiphany) concludes the season, where doors are marked with three crosses or the initials K+M+B (Kaspar, Melchior, Balthazar) using blessed chalk.

Midwinter, Candlemas, and St. Agatha

Pusiaužiemis (Midwinter) falls on January $25$. It is a turning point where the day has lengthened by one hour since the solstice. Weather is predicted by the badger: if it sees its shadow and returns to sleep on its other side, spring will be late; if it stays out, spring is near. It was also known as "Snake Day" when reptiles were believed to wake briefly.

Candlemas (February $2$, Grabnyčios) is also called "Perkūnas Day." It is the first breath of spring. Thunder candles (grabnyčios) are blessed in church, used as protection against lightning and for the dying. St. Agatha’s Day (February $5$) focuses on the fire goddess Gabija. Blessed bread and water are kept to protect against fire and the "evil eye," and used in folk medicine.

Užgavėnės: The Threshold of Spring

Užgavėnės (Shrove Tuesday) is a noisy, secular festival occurring between winter and spring. It involves eating heavily ($9$ to $12$ times a day) before the long fast. Foods include šiupinis (peas and fat with a pig's tail), pancakes, and meat stews. Ritual sledding is believed to ensure tall flax. Water dousing of "bees" (children hidden under blankets) encourages summer honey production.

Masks (ličynos) are central, representing zoomorphic (bear, horse, goat, crane), demonomorphic (witch, devil, death), or mythical figures. The struggle between Lašininis (Fatty) and Kanapinis (Hemp-man) depicts the transition from meat-eating to fasting; Kanapinis always wins. The festival culminates in the destruction of an effigy: Morė, Kotrė, Gavėnas, or Čiūčela. Burning or drowning these effigies cleanses the community and fertilizes the soil with ash. Celebrations end at midnight with the "Šambaris" dance.

Lent, Bird Holidays, and Palm Sunday

Lent (gavėnia) is a period of silence and strict fasting—meat, milk, and eggs were avoided, especially on Wednesdays, Fridays, and Saturdays. Ash Wednesday (Pelenų diena) involves scattering ashes to remember mortality and dragging logs (kaladė) to the houses of those who didn't marry. High-spirited "Bird Days" punctuate Lent: Lark Day (February $24$), St. Casimir’s Day (March $4$, the source of the Kaziukas fair and its palm/heart-shaped gifts), Forty Birds Day (March $10$), Lapwing Day (March $19$), and the equinox-linked Stork Day (March $25$).

Palm Sunday (Verbų sekmadienis) centers on the verba—a bouquet of juniper and willow. People are struck with it to grant health and growth with the chant: "The verba strikes, I do not strike; do you promise an egg?". Blessed verba are kept all year to smoke out storms or disease.

Holy Week and the Splendor of Easter

Holy Week involves ritual cleansing. Maundy Thursday is "Clean Thursday," involving sunrise baths and "Dead People's Easter" (Vėlių Velykos) visits to graves. Holy Saturday features the blessing of new fire and water. Easter Sunday marks the resurrection and the return of the sun. The name Velykos either means "Great Day" (Velykden') or is linked to the spirits (vėlės). Houses are decorated with trees of $9-12$ eggs.

Traditional Easter breakfast begins with the head of the family dividing a single egg among all. The menu features butter lambs, roasted hams, and high yeast cakes called boba. Easter activities include egg rolling, caroling by lalautojai who sing lalynkos with the refrain ai lalu lalu, and visiting godparents. The second day features dousing girls with water to ensure health. The third day is "Ice Day," when work is avoided to prevent hail.

Spring Fertility: Jurginės, Sekminės, and St. John’s Eve

St. George’s Day (April $23$, Jurginės or Jorė) is the first day of pasturing. Fields are blessed with bread and eggs buried in the soil. Pentecost (Sekminės) involves decorating with birch branches and the "Shepherd’s Feast" of scrambled eggs (pautienė). Cows are crowned with wreaths to increase milk.

Rasos or Joninės (Midsummer) celebrates the solstice through fire, water, and herbs (kupoliavimas). Fires on hills symbolize the sun, and jumping over them cleanses the individual. The mythical "fern flower" is sought at midnight, though seekers are warned not to look back. Dew collected at dawn is believed to heal and beautify. The summer cycle concludes with Žolinė (August $15$), the feast of greenery and new harvest, where flowers and vegetables are blessed in church, followed by a family feast of $12$ dishes.

Autumn Equinox and Baltic Unity

The autumn equinox is currently observed as Baltic Unity Day (September $22$), commemorating the victory at the Battle of Saule in $1236$. Fire relays are lit on hillforts. It aligns with Dagotuvės (St. Michael’s Day), the festival of the sprouted winter crops. Historically, a goat was sacrificed to the gods—particularly Velinas, ruler of the underworld—to ensure the survival of the grain through winter frosts.
