I've always been confused about how to correctly use prepositions before time. In this case, my intuition tells me that I have to use some proposition before this week, but the search result is suggesting that I shouldn't use any of them. If a preposition is not required, what is the underlying grammar under "the meeting this week"?

These websites might help you: https://textranch.com/25624/in-this-week/or/on-this-week/

It is much more common to say "during this week," or simply, "this week."


When we say last, next, every, this we do not also use at, in, on.

We'll call you this evening. (not in this evening)

  • Thanks for sharing the articles! I wonder which grammar makes not using any prepositions before last, next, this, every correct. Dec 6, 2021 at 3:48

    I can't find very much on the internet to back me up here as for why, but I can just tell you that "this weekend" is more correct. I've got more links to forums that answer the same question, and all simply say it is more correct. One notes that "on this weekend" is a bit archaic. hinative.com/en-US/questions/15235675 italki.com/post/question-148676 Sorry I can't help more here.
