Of course, almost every weekend is these days, but this time period especially so, considering it's also the holidays. Either way, we have to thank WOTC for keeping us updated.
In this particular case, we can thank Nate Price, or WOTC_Nate as he's known on Reddit. Anyway, he provided a really detailed list (including PTQs!) of upcoming events for the next few weeks, and it's well worth checking out!
