Best times to post for max karma?

I post a lot but I'm not really sure when the best times are to get the most karma. I've posted at times when there's just a little activity and I end up getting 1 kettle, post again and there's a lot of activity and I get a few upvotes. It might be a stupid thing to ask but I've seen questions like this in the past so I'm not the only one, probably lol<br><br>I'm curious
