The NFL released an updated calendar that carries us all the way through to the 2016 NFL Draft. Next year's draft is officially scheduled for April 28-30. I've embedded the full updated calendar down below. I'll be creating a calendar page to add to the library up top later this week.
The most notable upcoming dates are September 1 and September 5. On the 1st, teams must reduce their roster to 75 players. On the 5th, they must reduce their roster to the 53-man limit. After that final cutdown, waivers runs at 9 a.m. PT on September 6.
