Exercise: Prepositions of time (at, in, on)

In this exercise, you'll practice the prepositions of time: at, in, and on. Here's a quick summary: "On" is used for days and dates (like on Monday, on January 1st), "in" is the best option for longer periods like months, years, and parts of the day (like in September, in 1995, in the afternoon), and "at" is used for specific times (like at 3 PM, at midnight). The correct answers for the quiz are: We have a meeting at 3 PM. I was born in 1995. The party is on Saturday. He called me on Friday afternoon. The train arrives at midnight. My birthday is in September. The show begins at noon. We go on vacation in summer. The store closes at 6 PM. The exam is on Monday morning.
