Haha fair play, but to nitpick in return: when I worked on FB Ads, revenue was not even remotely uniformly distributed across days of the year, and Thanksgiving? Lots of family photos going up and being looked at relative to your typical Thursday.
Morbidly funny anecdote: when I first moved to the NYC office I obviously didn't have many friends, let alone a significant other. Myself and a few of the other sad saps who failed to notice the office clearing out a bit early around us were borderline freaking out over what looked like very anomalous behavior in the IG ranking system.
It wasn't until we raised it in a slack group that included some coupled folks that we realized it was Valentines day. Womp Womp. ;)
