Leading up to midnight on Nov. 30th, everyone's online posting ("38 minutes to go!!!!") and in the wee hours the few who hear at midnight post a million times and have a bit of celebration/sadness.
Then there are 2-3 days of pure agony as people wait for the actual letters.
So honestly, there is very little that happens on the actual first, since AADSAS updates at midnight for most schools that will bother with it. Quite funny!
At least, that's how it was last year....
