What are the dates for the 13 period accounting?

Answer 1

While most companies end their year on December 31st or the last calendar day of some other month, there are a great many companies whose year will end, for example, the last Saturday in December or some other month.

Generally speaking, these companies will divide each quarter of the year into three monthly periods consisting of two four week “months” of 28 days each and one five week “month” of 35 days, hence the name 4-4-5 Week Accounting Periods.

13 Period Accounting: The 13 Period Accounting module is the same as the 4-4-5 Week Period Accounting except that the tax year will consist of 13, 28 day accounting periods. Let's assume your 13 period started on a Monday, Jan 1 2007. Your last day of this period will be Dec 30, 2007. Your next period will start on Dec 31 2007, again, a Monday.
