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 (we’ll use this as we go):
-
at → for specific times (like 3 PM, midnight, noon) or short periods like “the weekend” (sometimes), “night”, “dawn”, etc.
-
on → for days and dates (Monday, July 4th, my birthday, New Year’s Day)
-
in → for months, years, seasons, centuries, long parts of the day (morning, afternoon, evening — but NOT with “night”)
