AT ON IN - Prepositions of Time

English Grammar Rules

AT

We use AT with specific times (hour / minutes):

Midnight (and midday) is a specific hour which is why we use AT.

12am = midnight
12pm = midday / noon

We use AT for a holiday period of two or more days:



ON

We use ON for specific days and dates:

Remember that for dates, we use ordinal numbers.

E.g. the First of September (not the one of September)


IN

We use IN for specific months, years, seasons, centuries and lengths of time.

Compare:

The New Zealand National day is in February.
(I don't mention the day - only the month)

The New Zealand National day is on February 6th.
(I mention the day - the order is not important)
