Lunar Calendar

I was recently looking for a Lunar Calendar for use in a Curse of Strahd campaign I’m going to run soon, but couldn’t find any that suited the needs of a fantasy campaign. Most real lunar calendars either do not truly follow the phases of the moon or are difficult to use as the a lunar cycle is not consistent. I have tried to solve those problems with the following calendar. There are 12 months with 28 days each. There are no need for weeks since the moon’s half, full and new phases serve as natural holidays and the gibbous and crescent phases serve as workdays. As I was making this for Barovia where the first the month is the Full Moon, unlike most real lunar calendars which have months starting on the New Moon, the First Quarter would occur last and vice-versa. So, I’ve renamed the First and Last Quarter the Right and Left Halves. The suggested season and month names are also meant for Barovia, but feel free to change them.
