Slightly off topic but related, so I’ll post here in an attempt to be helpful. Mods can move it if there’s a better place. I spent quite a while last night and today trying to figure out what I will need to do for testing and when. (Important because one day before my departure is New Years Day. Are the labs open? Which ones? Where? Etc...)

Here is the best info I found. As far as I can figure it is accurate as of today. I assume changes will be poster here as they occur.

Hope that helps.
