I would like to add more holidays into the game (if at all possible). Messing around with NRAAS Tempest allowed multiple instances of holidays per season, but they had the same name (for instance, I tried to add another holiday in winter but it was also called Snowflake Day as well, which is not what I want).

I'm fairly new at this, but any help would be appreciated. I have only messed around with Retuner and Tempest, have no idea of any other ways.
