Prisawen Calendar

The Prisawen solar calendar is an arithmetical calendar. It counts days as the basic unit of time, grouping them into years of 365 or 366 days. The solar calendar repeats completely every 146,097 days, which fill 400 years, and which is approximately 24350 six-day weeks. Of these 400 years, 303 (the “common years”) have 365 days, and 97 – the leap years – have 366 days. This additional day is traditionally known as the Radasheni. This gives an average year length of exactly 365.2425 days – or 365 days, 5 hours, 49 minutes and 12 seconds.
