Short format: dd/mm/yyyy (Day first, month and year in left-to-right writing direction) in French and Fulah. Gregorian dates follow the same rules but tend to be written in yyyy/mm/dd (Day first, month number, and year in right-to-left writing direction) format in N'ko language.

For example, the year cannot be divided into twelve 28-day months since 12 times 28 is 336, well short of 365. The lunar month (as defined by the moon's rotation) is not 28 days but 28.3 days.

A calendar date is a reference to a particular day, represented within a calendar system, enabling a specific day to be unambiguously identified. Simple math can be performed between dates; commonly, the number of days between two dates may be calculated, e.g., "25 February 2025" is ten days after "15 February 2025".
So although the year 2000 was a leap year, the years 1700, 1800, and 1900 were common years. The International Fixed Calendar inserts the extra day in leap years as June 29 - between Saturday June 28 and Sunday Sol 1. Each month begins on a Sunday, and ends on a Saturday; consequently, every year begins on Sunday.

All of these events can have wide variations of more than a month from year to year.
