In, On, At – Prepositions of Time

Sharing is caring!

Prepositions of time are the same words as prepositions of place, however they are used in a different way. You can easily distinguish these prepositions, as they always discuss times rather than places.

A preposition of time is a preposition that allows you to discuss a specific time period such as a date on the calendar, one of the days of the week.

Prepositions of Time

Generally, in shows the “largest” time, on shows dates and time, and at usually shows the “smallest” time.

English speakers use in to refer to a general, longer period of time, such as months, years, decades, or centuries. For example, we say “in April,” “in 2017” or “in the 21st century.”

Moving to shorter, more specific periods of time, we use on to talk about particular days, dates, and holidays . You may hear, “I went to work on Monday,” or “Let’s have a picnic on Memorial Day.”

For the most specific times, and for holidays without the word “day,” we use at. That means you will hear, “Meet me at midnight,” or “The flowers are in bloom at Easter time.”
