Year represents approximately 365 earth days. The year is divided into seventy three segments (73) each of five Days, except a Great Year (every 4th year) when an additional day shall be added to the last Arc except every 128 years (Jubilee) when an extra day shall not be added, and every 128,000 years (Great Jubilee) when the extra Day will be added.

In comparison to Gregorian time a new Sun Year begins every December 21.
