Stanford Restrictive Early Action

I plan on doing Stanford’s Restrictive Early Action, and was wondering if how early you apply matters. I know that many schools have rolling admissions and it makes sense to apply as early as possible but will it help my chances if I submit everything on the first or second day that it is open? Thanks!

They dont look at anything until the deadline has passed, unlike rolling admissions. It will make no difference when you submit as long as you do so before the deadline.
