Kickoff: Always the first Saturday in January, unless it's deemed too close to New Year's--which happens to be the case for 2016. January 9th it is. (Source: FRC official calendar)

Any given regional... add 6 weeks to the Kickoff, so either the last weekend in February or the first weekend in March is Week 1. Add 5 more weekends. Somewhere in that window is where the regional in question will land.

More specific regional dates will have to wait for August or so, as venue contracts are signed.
