The calendar round of 52 solar years based on the Haab 365 day cycle. The Calendar Round is 18,980 days.
18980 Calendar Round days divide it by 365 solar years (Haab) = exactly 52 years
or 365 x 52 = 18980 days
Now this can't be done with the Gregorian calendar...
18980 Calendar Round days divide it by 365.2425 solar years =
or 365.2425 x 52 (Haab solar calendar round) = 18992 days
As you can see above, the Gregorian calculation is completely off from the Haab solar Calendar Round!
