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.
- At the moment, at present, at that moment.
- In the past, in the future.
Remember: we don't use in/on/at when we say "this / last / next".
I'll see you next week.
