On or in your holidays

[Jignesh77]

What will you do in/on your holidays ?
It's a made up sentence (interrogative).
Which is the correct preposition and please explain why?

 

[lingobingo]

It’s not written in stone, but the most usual collocations are “on my holidays” (my vacation) and “in the holidays” (the school holidays).

 

[Jignesh77]

Which one fits the context in my example?

 

[lingobingo]

You haven’t told us the context! But, as I said, with my (or your, etc.) we’d probably usually use on.

Thanks!

I'd say "What will you do in the holidays?" or "during your holidays".

Thank you!
