    Now there are three separate independent "passive analogue" mathematical models: for lunar, solar and luni-solar calendars which does not take into account a system error. The uniform universal mathematical model for all the three types of calendars does not exist. In the article author offers the uniform universal "active digital" mathematical model for all the existing types of calendars which takes into account a system error.
