7 x 7 x 7 Calendar

As a continous 7 day week is important to several religions,
what would it be like if we extended the groups of 7.
Let’s say to have seven “septims” of seven 7 day weeks.

7x7x7 = 343 so it fits into the solar calendar, leaving 22/23 days.

These tables show the start date of each period, with year starts from near the solstice (21/22 December), Western and Eastern Xmas and March 1st.

Starting the year with 7 septims.

Ending the year with 7 Septims.
