How to schedule a Tier 3 Reckoning Run (Fireteam Builder Events)

Need to do another 4 runs of Tier 3 to get my Notorious Helmet. Really enjoyed the FTB event that I was able to join and was wondering how it was scheduled for the optimal perks?

I've done some light googling and I get that there's a schedule of some kind, but I can't easily figure out how to apply it to the future.

Thanks for any help!
