English uses three main prepositions for time: at, on, and in. Each one is used for a different kind of time.
AT — for specific times and fixed expressions: at 3 o’clock, at noon, at midnight, at night, at the weekend (British English), at Christmas, at the moment “The meeting starts at 9 AM.”
ON — for days and dates: on Wednesday, on Friday morning, on 15 March, on my birthday, on New Year’s Day, on the weekend (American English) “She was born on the 5th of June.”
IN — for months, years, seasons, and longer periods: in January, in 2010, in winter, in the morning/afternoon/evening, in the 19th century “We moved here in March.”
No preposition with last, next, this, every, tomorrow, yesterday:
✗ “I saw him on last Monday.” ✓ “I saw him last Monday.”
