At weekends vs. At the weekend

[abc]

Hi teachers

Is there any difference between these two phrases? (At weekends vs. At the weekend)

Also, how to use them?

Thanks in advance

Hi abc

British English:
"At weekends" refers to weekends in general.
"At the weekend" would refer to one specific weekend.

In American English, you would use "on" instead of "at" to say the same thing.
