A list of revisit dates for schools was requested, so here ya go! Add some in alphabetical order if you know.
SPS: April 1, 2, 4, and 5
Also there is an old thread with info on this but don’t use it because its not reliable for this year. 
Thanks very much!
Berkshire: The website says “early April”
Canterbury: March 30

Lawrenceville: March 28, April 4 and 6
SMS: April 2 and 4

For those looking at mid-Atlantic schools:
Mercersburg is March 25
EHS is March 31/April 1
SPS revisits are two-day long, so there are only two options: April 1-2 or April 4-5 (not April 1, 2, 4, and 5)

Peddie has 3/28, 4/2, 4/3 on their 2018-2019 calendar but 3/27 and 4/2 on their month to month calendar.
My guess is 3/27 and 4/2.
edited to add that the 2018-2019 calendar is from over the summer

Are revisits usually the whole day?
This is wonderful. Can I ask where you found these? I scoured the websites of several of the schools on this list for days and couldn’t locate them for the life of me.
Keep them coming! It’s most helpful for planning (hopefully!) for March and April.
I looked on the schools academic calendar. The same calendar a parent with a kid currently at the school would check to see vacations, etc. I also called one school.
