Football is pretty much a weekend sport, although a few games are played on Monday and Thursday, particularly in the NFL. In general, however, the football season, which begins in earnest right around Labor Day, follows this orderly pattern:
High school games are usually played on Friday nights.
College games are played on Saturdays, mostly during the day, although a few are held on Thursday and Friday nights.
The NFL plays on Sundays for the most part. For television purposes,games are played in the early and late afternoon (Eastern time).
