While the year used to be based off the moon cycles (Yadellna or moon year), this has changed in preference to the solar cycle (Yasha).

There are 8 months leading up to solstices, equinoxes, and points in between.

Each month is composed of:

• 8 regular weeks of 5 days.
• 4 to 6 celebratory days (Levannas.)
• The holiday proper.

The day in the month is referred to as Morning-Day-Week, which is counter-intuitive to what we expect.

• The first day of the week is actually 10.
• The first week is 1.
• Combining these gives us 11 for the very first day.

The 2nd day of the week is 20, which would mean that the day following day 11 is actually 21, then 31, 41, 51, to end up to 12, 22, 32, and so on.

This strange arrangement is made to preserve the week number at the single digit level. For example, if one person simply says “Day 1”, it basically means “any one day during the first week”.
