Still in the works, but the following will be true.
There are 20 days in a Cycle.
4 Cycles in a Phase,
And 4 phases in an Age.
Writing the date is easy: 1/2/2/756
or First day of the Second cycle of Lyr, in the 756 Age of Alysia
Phase Names: Kron, Lyr, Brim, and Styx
Kron is the phase of renewal – Winter
Lyr is the phase of love – Spring
Brim is the phase of life – Summer
Styx is the phase of death – Autumn
Thus the phases rotate with the start of each new age.
