Prepositions of Time: In, On, At

Prepositions of time are small but important words that show when something happens. The most common ones are in, on, and at. Learning how to use them correctly will make your English sound much more natural.

We use on for specific days or dates. For example, on Monday, on Friday, or on the 15th. It’s used when we talk about one particular day.

We use in for longer periods, such as months, years, and parts of the day. For example, in July, in 2024, or in the morning.

We use at for exact times and special moments. For instance, at 3 PM, at noon, or at midnight.

A simple way to remember:
• In = longer periods
• On = specific days
• At = exact times
