Let’s go through each sentence one by one. We’re choosing between
at,
in, and
on for time expressions.
Here’s a quick reminder (you don’t need to memorize it — just think about how we use these words):
-
at → for specific times (like 3 PM, midnight, noon) or short moments (“at night”, “at the weekend” in British English — but here we’ll stick to standard rules).
-
in → for longer periods like months, years, seasons, centuries, parts of the day (morning, afternoon, evening — *except* when we say “on Monday morning”).
-
on → for days and dates (Monday, July 4th, New Year’s Day, my birthday).
