How the system works:

-The year is divided into 73 cycles, each associated with a specific Greek deity, and each lasting 5 days, with the exception of the Selene cycle, which may last 6 days to synchronize with Gregorian leap day reckoning.

-Years begin on the Hestia cycle, specifically Aether of Hestia, which is January 1st per the Gregorian calendar, and conclude on Water of Hera, i.e. Gregorian December 31st.

-Days begin at midnight and are named after classical elements in a fixed sequence: Aether, Fire, Earth, Air, Water. For example, the Pan cycle (June 10-14) would have:
Aether of Pan (June 10)
Fire of Pan (June 11)
Earth of Pan (June 12)
Air of Pan (June 13)
Water of Pan (June 14)

-When a leap year occurs in the Gregorian calendar, a "Wood" day is added following Air in the Selene cycle (February 25-March 1), making it 6 days long instead of 5.

-Dates in this system can be represented as: 1) [Element] of [Deity], [Year] or 2) [Day Number within Cycle] [Deity], [Year] or 3) [Day Number within Cycle] / [Cycle Number] / [Year]. For example, today's date is September 20, 2024, or as in this system, Earth of Rhea, 2024; that is, 3 Rhea, 2024; 3/53/2024.
