My source:speculation, based on past performances.
However, I am beginning to think it may be the 30th rather than the 23rd. That was my original thought back a few weeks ago, but several people on here said, no, it would be the 23rd.
But looking at the calendar and looking back at last year, the decisions came the Friday AFTER Spring break ended. This year's Spring break is this coming week. So the Friday AFTER it ends would be the 30th. Also, there are five Fridays in this March, whereas last year there were just four. So it could well be the 30th.
If you aren't confused now, you'll never be. Also, Mt. Holyoke usually comes out with theirs a week ahead of Smith. Looks like theirs will come out next Friday since no one has heard anything today. So stay tuned.
