Common Calendar

The Common Calendar is the calendar used in most of the world. It was introduced in June of 1437 by the Society of Gandorists, who sought to create a standardized way of measuring the date. The calendar set the length of a year at 365.2425 days, in addition to setting the year of the Great Collapse the beginning of a new era. Unlike the Gregorian Calendar, the Common Calendar has a Year 0, which denotes the year the Collapse occurred.

Usage of the Calendar
A calendar year is either 365 or 366 days, depending on whether or not it is a leap year. There are a total of 12 months, which contain 30, 31, or, in the case of the second month, 28 days. In a leap year, the second month will have 29 days to compensate.

Years occurring before the Great Collapse are styled BGC, while years after are styled AGC.

Months
The names of months in the Common Calendar are different from those in the Gregorian Calendar. Nevertheless, this wiki utilizes Gregorian names for ease of browsing for readers. The original month names used by the Gandorists are listed here. Different nations may use different names, although the lengths of months and the year should remain consistent.
