Using in, on and at
The triangle here shows one general rule for in, on and at - the times usually get longer from at to on to in.
AT: use at with times
- I got married at 3.30.
ON: use on with days and dates.
- I got married on December 31st.
- I got married on Saturday.
- I got married on New Year's Eve
IN: use in with months, seasons and years
- I got married in December.
- I got married in the winter.
- I got married in 2007.
Remember: we don't use in / on / at when we say this / last / next.
I'll see you next week.
Here are some other examples you should learn:
- in + the morning / the afternoon / the evening (but at night)
- at + mealtimes (at breakfast, at dinner ...)
- at + the weekend / weekends
- at + well-known holiday periods (at New Year, at Christmas)
- at the moment, at present, at that moment
- in the past, in the future
