5-4-4 Accounting Period

The 5-4-4 accounting period setup generates 12 new periods starting from the Period 1 Start Date for Start Fiscal Year. Each period length varies, but the periods are structured in a 5 week /4 week/4 week repeating pattern.

Because special multi-period accounting schedules are only 364 days long, the calendar must be periodically readjusted in order to remain accurate. Every 5 or 6 years, an extra week is automatically added to the last period of the calendar. This addition happens in the 13th period for 13-Period and in the 12th period for 4-5-4, 4-5-5, or 5-4-4.
