Prepositions of Time – At – In – On

Prepositions - at, in, on

The prepositions of time at - in - on allow you to discuss a specific time period such as a date, a day of the week, or the actual time an event takes place.

"We're going to the cinema on Monday night".
"These animals hibernate in Winter".
"The plane takes off at 19.05pm".
