ON/AT

[SARDORBEK]

Dear TEACHER!

I don’t have anything on/at this weekend.

Which preposition in bold is correct? Is one of them strictly used or is there any difference between American and British English?

Thanks a lot…

Your intended meaning is unclear.

If you mean 'I have no plans for the weekend', then you could say (in BrE or AmE)

I don't have anything on this weekend.

but 'on' here would be an adverb, not a preposition, a part of the phrasal verb 'have on' (= have as a plan), and therefore unconnected with the noun 'weekend'.

The regular preposition for 'weekend' is 'at' in BrE and 'on' in AmE, so that BrE

I often go away at weekends.

would become in AmE

I often go away on weekends.

I trust this answers your query!
