Astronomy and The Aleran Calendar

The Aleran calendar is divided into 12 months of 28 days each, except for December, which holds 29, the last day on which the year ends and the next begins. Alera has three moons; the closest and smallest is white and is named 'Ilkay' (first moon), the second is larger and is named 'Tuncay' (bronze moon). This moon is further away and has a bronze tinge to it. The last and outer most moon of the three, is also the biggest and is amply named 'Koray' (ember moon), as it appears almost red at times.
 * A day is how long it takes the planet to revolve on it's axis once
 * A month is how long it takes for the three moons Ilkay, Tunkay and Koray to revolve around the planet
 * A year is how long it takes for the planet to revolve around the sun
