​AT

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

• I get up at 7 o'clock.

• My English class starts at 10am.

• She finishes work at 6.15

• I left the party at midnight.

​

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:

• Do you normally get together with your relatives at Christmas?

• Did you eat a lot of chocolate at Easter?

​ON

​We use ON for specific days and dates:

• I will return it to you on Wednesday.

• They got married on Friday the 13th.

• We get paid on the 20th of every month.

• I drank too much milk on New Year's eve.

​

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.

• My birthday is in January. (I don't mention the date, just the month)

• My grandmother was born in 1927.

• The river near my house is dry in Summer.

• The company was founded in the 19th century.

  We need to have this report ready in 15 minutes.

Compare with on:
