Prepositions

Use IN for long periods (months, seasons, years), ON for days and dates, and AT for specific times or exact points. Keep these little rules in mind! 😉

Preposition

Use for Time

Examples

Easy Trick to Remember

IN

Months, Years, Centuries, Seasons, Long periods

in September, in 2025, in winter

Inside a big timeframe (a month, year, season)

ON

Specific days, dates, holidays with “day”

on Monday, on 4th July, on New Year’s Day

Imagine a small spot like a pin on a calendar.

AT

Exact times, specific points in time

at 12 o’clock, at midnight, at the end of the week

Precise moment like a sharp time point.
