English Grammar Prepositions of Time ‘In, On, At’

Thanks for checking out my latest article about English learning. In this article I am going to talk about prepositions of time.

The most common prepositions in the English language are ‘in,on,at’ and the reason I wanted to talk about them was because when I am teaching English grammar or just doing English language exercises students are always asking me to explain them.

The preposition of time – ‘in’ is used for months, years, centuries and long periods.

Here are some examples:

  • in January/May etc.
  • in 2006/1970 etc.
  • in winter/summer etc.
  1. I’m going on a business trip in August.
  2. David was born in 1969.
  3. The garden is beautiful in summer.
