Today I was kinda bored and I was thinking about this: Princesses Celestia and Luna control the Sun and the Moon, thus the day and the night. If they can control the lenght of a day, they could also decide on the lenght of a week, a month, a year, etc., all in all, ponies have control on "time", unlike humans. So I guess an Equestrian year wouldn't be 365.25 days long, that would be too much trouble for nothing; why not 360 days? Or even 300 or 400 days? That would only be logical for a species that possess such power on its environment.
What would the Equestrian calendar look like? How many days a year? How many months (and what would be their names? Julius Ceasar didn't exist and couldn't give his name to July)? How many days a week? How many hours a day? Etc.
