Custom Widget to Count Down Days/Hours to Next NBA Game

I’m not sure exactly how to do this, but I was thinking it’d be cool to figure out a way to build a custom widget that would tell me how many days and hours there were until the next NBA game for my favorite team(s). Does anyone have any leads on how to make something like that? I’m a complete novice, so I might be dreaming too big for something that I’d be capable of doing. :grimacing:
