December 20th-22nd (next Wednesday through Friday).
What Is It?
The early National Signing Day is a chance for colleges to go ahead and sign any of its commits to a scholarship. It is the same thing as the current National Signing Day, except it takes place in December instead of February.
Any given team is expected to sign around an estimated 80%+ of its 2018 recruiting class, so this is becoming the de facto National Signing Day(s) for college football.
What this means is that instead of waiting until early February to sign (like it has been done for years), there is now a period where 2018 commits can sign their National Letter of Intent early and be locked in to a scholarship with their respective school without waiting another month and a half.
