Worth knowing

at, in and on: three small words for saying when

English needs a small word before most times. Which one you use depends on how big the time is.

for a clock time: at six o'clock, at midnight for a day or a date: on Monday, on 5 May for a longer time: in May, in 2026, in the morning

Think of it as getting bigger. A point in the day is at. A whole day is on. Anything longer is in.

The exceptions are few

Say , not in night. This is strange, because you say in the morning and in the evening. Night is the only one that is different, and you simply have to remember it.

Say in British English. American English says on the weekend. Both are correct in their own country.

No word before today

Some time words take no small word at all:

  • I saw her . (not on today)
  • We leave .
  • He came .
  • She starts .

Today, tomorrow, yesterday, last and next never take at, in or on. This is a common mistake and an easy one to fix.

last night

There is no word yesterday night in English. The correct phrase is .

But yesterday morning and yesterday evening are both fine. Only the night is different.

early, late, soon

and describe a time. describes a short wait from now.

  • The train was late.
  • I will see you soon.
