DMF a week early and world buff drops in new zones, bugs?

Hi, DMF has begun setup a week early on my realm Arugal. The setup is suppose to happen first friday of every month so the faire can begin a few days later, but it’s a week early setting up for may when it’s still april.

Also there’s been instances of world buffs from ony/nef/rend dropping in durotar and elwynn forest today. It’s been posted around the large class discords and seen by friends screenshots. This may have already been fixed because I couldn’t get them in durotar just before this but yeah they have been dropping.

Surely the DMF cycle we’ve had all the way from vanilla to shadowlands being changed can’t be intentional? Maybe some bug with the recent hotfixes?

Edit: The retail calender says it’s right to spawn this weekend, and it also shows 2 dmf’s in the same month in november so I guess there is no first friday of every month formula and it just happen to be correct for every month of classic so far, or they recently changed it.
