4-5-4 Calendar Table



I need some help creating a date table for my company.

This table should start in 1999, but the actual fiscal calendar started 1/1/2001. Every 5 or 6 years December has a 5th week.  This is because the 4-5-4 is exactly 91 days. 91 days x 4 quarters = 364 days per year. So we lose a day each year in accounting.  When you add in February 29th every 4 years we lose another day. Eventually, we would end up with the year ending earlier and earlier.  The December 5th week is to correct that.  Coincidentally 2021 is a 5 week December (see attached).

Hi @hayesla96 


In addition to 2021, which years have the fifth week in December from 1999?
