Do holiday's have a full-moon effect on HCBM's?

Things have been relatively quiet for a couple weeks, then BOOM today, she calls my FH's work asking them to get him a message to call her. He has a no contact order due to her stalking him, and is only allowed to contact him via text if there is an emergency with SS10. He calls her.....thinking it's an emergency.....nope, she wants to know who is watching him on Friday because there is no school. She has been told time and time again, by the case manager, the mediator, and the judge that what happens at our house is our business, not hers. FH reminds her of this, and of the restraining order. She then goes off the deep end, telling him that he ruined their lives, and because of him and me, her other children need therapy, blah, blah, blah. He hangs up on her, she calls back, he doesn't answer, she starts texting. She sends this big long message about how sad she is, and how much she misses her family, and how she can't believe FH up and left (nothing about her cheating), then a minute later texts back, sorry, that was meant for my friend, not you. Hope you have a happy Valentines day.

Seems like she will find any reason to contact him on a "holiday", it's really annoying.
