f67r2 and potential link to length of months

[pjburkshire]

 This reminds me of how lunar calendars tend to have alternating months of 29 and 30 days, until sometimes there are successive 29 then successive 30 day months. It seems to me that f67r2 suggests this idea with the yellow and red colored moons.

Yes, I think f67r2 is about the Moon. I think their Astrology system included both the Sun and the Moon.
