[Discussion] Best time to query holiday themed books?

In your opinion, is there a "right" time to query holiday themed books?

I've noticed that when I was selling holiday-themed crafts on Etsy, it was best to put out the product 3 months before the said holiday, like what retail stores do.

And there was that post where someone queried their book, and it was quickly accepted because the agent believes the book was coming at the right time due to the election and the theme of the book.

1. So, I was wondering if there's a timeline to query for holiday-themed books?

2. And in general, are there months that you just absolutely avoid querying for personal or technical (it's a holiday so no one is checking their emails, etc) reasons?
