the year is composed by 500 days, divided in 10 months of 50 days, it is the calendar in which all the history of Vorogar is recorded, and it never resets in favor of being an universal calendar indipendent from outside happenings, so that the entirety of history is recorded properly.

The Scribes calendar is, instead, the most ancient of the three, and is now not used anymore, except by the Order of Chronos' Scribes, who to document the happenings of the world since their foundation, which is regarded as the year 0 on the calendar

This calendar too does reset, this one every "alignment" which means when the three moons are aligned within each other, an astronomical event that happens roughly every 3000 years, so far there has been four alignments, with the first one marking the start of the Lunar calendar.

each month lasts 15 days, and in a year it completes 5 cycles, making it so a year has 20 months (the four months being New Moon, Rising Half, Full Moon and Lowering Half) the smallest moon goes through each of its phases every 5 days.

Let's move onto the Lunar calendar, which bases itself off the cycles of the three moons of Vorogar, the year (composed of 300 days) is marked by a full cycle of the biggest moon, instead each month is marked by a phase of the second moon

More interestingly, this calendar resets every time the Sun God, Atoq, is summoned (which happens roughly 2500 years usually) and so far it has happened five times, the calendar has actually started being used the first time Atoq was summoned on Vorogar.

these periods are usually also divided in "weeks" composed of 5 days each, to a total of 320 days per year.

The solar calendar is the most used calendar of the three, it tracks, or at least used to track, seasons, it's divided, in fact, in four months (Spring, Summer, Fall and Winter, in that order) each composed of 80 days, and divided in periods of 20 days (Calends, Ides, Nones and Quintils)
