The Arborlarian year is broken down into 12 Cycles. The first 6 cycles are known as the Approach, and the second 6 are known as the Retreat.
Each Cycle is broken down into 3 tendays, and each tenday is ten days long.
People throughout Arborlaria have two ways of referring to dates. The first, is by the day and the Cycle. For example, the 13th Day of Futhor. The Second way is a more traditional way, and that is by the day, the Tenday, and the Cycle. For example, Day 3 of the Second Tenday of Futhor.
Each year, for 5 days, people celebrate the Moon festival. It is a time of feasting, a time to honour ones god, and a time to pray for a good retreat and hope that the retreat is not too harsh. In the skies above, the three moons that circle Arborlaria come together on day 3 of the festival and form a perfect triangle. It is said, that any child born on this day, would be blessed by the gods.
