the image shows 2 rings (outer / inner radius 323 / 53, 252 / 89) with 4 gregorian calendar dates in 2 formats each.
(if you want to recalculate: convertxy.com...)
example: april 9th 1980 = 904 1980 (904 + 1980 = 2884)
(formatting rule for calendar dates would be: "for 'daymonth' use 3 and at least 3 digits whenever possible".)
how could the gregorian calendar be "linked" with geometry, given that geometry calculations clearly display gregorian calendar dates?
