When not to use in, on and at
There are certain situations when the prepositions of time are no longer needed in a sentence, and this usually happens before the following words:
each, every, last, next, this
For example, when using ‘this’ in the following sentence to specify a particular month, we would write:
- I am visiting Paris this April.
I am visiting Paris in this April.
Likewise, when using ‘every’ in the following sentence to indicate that something is a regular occurrence, we would write:
- He hates getting up every morning.
- He hates getting up in every morning.
Here are some more examples of when not to use a preposition of time:
- He visited the Colosseum last weekend.
- I am going back to school next week.
Students should also take note that prepositions of time are also not used before “the day before yesterday“, “yesterday“, “today“, ‘tomorrow‘ or ‘the day after tomorrow‘.
- I was made redundant the day before yesterday.
