Jehovahs Witnesses do not observe holidays they believe to have pagan origins, such as Christmas, Easter, and birthdays. They do not salute the national flag or sing the national anthem, and they refuse military service. They also refuse blood transfusions, even those that could be life saving.

Can you leave being a Jehovah Witness?

The only way to officially leave Jehovahs Witnesses is to disassociate or be disfellowshipped, and both entail the same set of prohibitions and penalties, with no provision for continued normal association.
