This means there is a "calendar holiday" entry in your database that does not have an end date; I wonder if that should really happens (even if it seems to be currently permitted).
As a workaround, adding an end date should do the trick.

[trasher]

BTW, I've just tested, and that does not seems a legit case: when creating a holiday, if you do not give an end date, it's set to start date automatically.

Ok.I Understood the problem. Thanks for orientation

thank you @trasher This bug causes many problems with processes that use the calendar. I had been having problems for several months and could not find a solution. Thank you for explaining it.
