Prepositions in English are difficult simply because there are often no rules! Once again we're dealing here with a grey area in English grammar. The good news is - there are some rules. Let's take a look at the basics of prepositions in English:
- For time, use 'at' - at 3pm.
- For days, use 'on'- on Wednesday.
- For parts of days, use 'in'- in the afternoon.
- For months, use 'in' - in April.
- For years, use 'in' - in 2020.
- For weekends, use 'at' - at the weekend.
- However, we say 'at' the beginning, 'in' the middle, and 'at' the end of something.
- The preposition, 'to', usually has something to do with movement -you drive to work.
- When referring to an enclosed area, use 'in' - 'Let's meet in my office.'
- So, when movement is involved, we use 'into' - he walked into my office.

That's more or less it. Some people suggest, learning prepositions in English with certain verbs. For example: to be interested in something or to look forward to something. However, for many, it's a question of gut feeling. Good luck!
