Every important date to know for 2023-24 NFL season

Mark your calendars for these important dates and deadlines on the 2023-24 NFL schedule.

Technically, the start of the 2023-24 NFL season began on March 15, which coincides with the league new year. That's also when free agency began, even though teams negotiated with players two days before, and that segwayed into the always-entertaining NFL Draft season.

Then, the boring hiatus.

The NFL is back, though, and the real calendar kicks off with the annual Hall of Fame game from Canton, Ohio, which is part of the Pro Football Hall of Fame's induction ceremonies for this year's class.

This year, the beginning of the preseason will feature both the Cleveland Browns and New York Jets in a meaningless but "thank goodness football is back" showdown on Thursday, Aug. 3.

The preseason begins shortly thereafter.

So, fans of both the San Francisco 49ers and the rest of the NFL, mark your calendars for these important dates on the upcoming 2023-24 season.
