The NSA State Championships have always been the 4th of July weekend as it still will be this year. Starting this year, there will be a North and South state tournament. The South will hold their state tournament the weekend prior to the fourth-of-July and the North state will be during the fourth-of-July weekend.
So you can see the pattern, these are the dates for future years:
