Calendar

The Veltherian unified calendar is shared between all of its cultures.

There are historical calendars maintained for archival reasons, which were once of cultural or religious significance before the unification of Veltheria.

Years
The years are counted positively from the first new year after the first Keystone was discovered, starting with AH 1, meaning 'in the first year of harmony’, from the Latin anno harmoniae. This means that by convention the day Maua was discovered, and the months that followed, fall in a previous era to the one named after the event.

The preceding age is called the Age of Nations, whose dates range from AC 1 to AC 4287. AC in this case stands for 'in the first year of nations', from anno civitatum. Dates prior to that are dated negatively, such as 1 SA ('ancient era', from saeculum anticus) being the year prior to AC 1.

Months
The Veltherian standard year begins, by convention, at the first dawn after the moment of the spring equinox (spring in Halsteyr, at least). The year proceeds as follows, with each month possessing 28 days, and an intercalary day falling in place of the 1st of the Bull's Moon (that is, the new moon following the equinox): Aside from a few special days where the phase of the moon is material, most of the time the months and moons are only loosely tracked.
 * Ram's Moon
 * Bull's Moon
 * Twin Moon
 * Crab's Moon
 * Lion's Moon
 * Young Moon
 * Fair Moon
 * Spider's Moon
 * Serpent's Moon
 * Goat's Moon

Days
Weeks are seven days long throughout Veltheria, though the names vary culture by culture. The system of Sunday, Monday, Tuesday etc is widely recognised.
