I live in the UK. The fireworks go on for up to a few days after Nov 5 (and even before). Also, because of the virus there were many more people letting off fireworks in their own gardens than usual since the government cancelled Guy Fawkes Night events.

Can't speak for anywhere else but where I live, nobody actually set off any fireworks at the specific period that he was announced President elect by the MSM. I half expected someone to, but I heard nothing.

Edit: just noticed it says London so I imagine they most likely did let off fireworks for Biden there. 🙄
