The Whole Weeks Calendar is a leap week calendar designed such that each period within it contains a fixed number of 7-day weeks. The basic calendar is the Symmetry 4-5-4 Calendar, with months of 28-35-28 days in each common quarter. But the leap week is placed according to McClenon's 5:40:400 leap week rules, with a leap week placed at the end of every fifth year, except for each 40th year not divisible by 400. While this is astronomically jittery, it forms a very systematic hierarchy of years, all of whole weeks at consistent, memorable intervals. The epoch of the calendar is Monday, January 1, 1 CE of the Gregorian Proleptic Calendar .

abstract	The Whole Weeks Calendar is a leap week calendar designed such that each period within it contains a fixed number of 7-day weeks. The basic calendar is the Symmetry 4-5-4 Calendar, with months of 28-35-28 days in each common quarter. But the leap week is placed according to McClenon's 5:40:400 leap week rules, with a leap week placed at the end of every fifth year, except for each 40th year not divisible by 400. While this is astronomically jittery, it forms a very systematic hierarchy of years, all of whole weeks at consistent, memorable intervals. The epoch of the calendar is Monday, January 1, 1 CE of the Gregorian Proleptic Calendar . The months are given hybrid names, with Greek numerical prefixes combined with French Republican terminals: Pentad The pentad is a five year cycle with 261 weeks, with a total of 1,827 days, unless it is the last Pentad in a common 40 year cycle. In that case, it has 260 weeks, with 1,820 days. Tettarakontad The Tettarakontad is a 40 year cycle with 8 Pentads of 2087 weeks, with a total of 14,609 days, unless it is the last Tetarakontad in a 400 year cycle. In that case, it has 2088 weeks, with 14,616 days. Tetrakosad The tertrakosad is a 400 year cycle with 10 Tettarakontads, of 80 total Pentads, containing a total of 20,871 weeks (71 of which are leap weeks) of 146,097 days. — Walter Ziobro
