How to use prepositions of time

Prepositions cause us trouble in any language we are learning. English is no exception. From my point of view, they are tricky because we don’t look at them systematically. In this post, I am going to show you a systematic approach to learning English prepositions of time. This way, they will be no problem for you anymore.

Basic time prepositions

These are at, on and in. They name different time lengths, namely points, days and time periods. We can put them into some kind of hierarchy to help us remember easier.
Let’s have a look at the main principle:



‘AT’ defines very short time periods, like moments and points.

We use ‘ON’ time periods equalling a day and all the phrases containing the word ‘day’.

‘IN’ is used with periods of different length, including parts of the day, months, years and so on.

You can watch this video for a detailed explanation on how to use these prepositions:

Now let’s move on to the intermediate prepositions of time.

It’s better to see these prepositions in contrast to each other because their translation can be confusing for speakers of different languages. I have grouped them together according to the similarity in their meaning. I give plenty of examples to show you how different they are from each other. You can see definitions and examples in the following table:
