Question for ED1 and ED2 admits

Have any of you been told yet when Swatstruck (or whatever else they’re calling admitted students day) is this April? I’m trying to put together a spreadsheet of all the open houses for all the colleges that kiddo applied to, so that I can book trains/hotels as soon as we learn results and I know which doctor’s appointments to cancel, but I couldn’t find those dates on the Swarthmore website. All it says is “in April” which isn’t much help.

Thanks.
