In the DPRS (communist), there are no birthdays. The "Dear Leader" is entitled to 37 Days of Birthday which has been extended for 5 years straight. This is the future tankies want.

Christmas isn't allowed either. Instead there's "Mandatory Christmas" which is only for the "Dear Leader" and lasts from December until August. People have to provide twice as many gifts to him each day. It has single-handedly collapsed the economy of the country multiple times but tankies will tell you that's "how it's supposed to work".
