To get the same mean year as the Gregorian Calendar this leap week is added to 71 of the 400 years in the cycle. The years with leap week are years whose last two digits are a number that is divisible by six (including 00) or 99: however, if a year number ending in 00 is divisible by 400, then Pax is cancelled.

This cycle breaks down into one 100-year period with 25 leap years, making 36,525 days, or one day less than 5,218 full weeks; and three 100-year periods with 24 leap years each, making 36,524 ...
Hanke–Henry Permanent Calendar pre-2016 version with weeks still starting Sunday, but Xtra already at the end of the year. In 2004, Richard Conn Henry, a professor of astronomy at Johns Hopkins University, proposed the adoption of a calendar known as Common-Civil-Calendar-and-Time (CCC&T), which he described as a modification to a proposal by Robert McClenon.
This is the calendar for any Old Style leap year starting on Monday, 25 March. The Old Style calendar ended the following March, on 24 March. Examples: Julian year 1616, 1720 or 1748 (see bottom tables). A leap year is a year with 366 days, as compared to a common year, which has 365.
Rather than a regular 365-day year, the leap year adds an extra day to “keep the calendar in sync with the seasons”. For a year to be a leap year, it has to be divisible by four or 400.
A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) compared to a common year. The 366th day (or 13th month) is added to keep the calendar year synchronised with the astronomical year or seasonal year . [ 1 ]
