When did fireworks on Christmas Eve in Houston become a thing?

They've been going off all evening around the neighborhood and they are freaking out pets. I don't ever remember it being a thing before. New Year's Eve yes, but not Christmas Eve. It's probably just kids not thinking of others. They're still going off now and no idea when they'll stop. I was just curious.

Edit: I'm not referring to little firecrackers, these are like AK's, heavy duty stuff, all evening, and not just in one spot.
