BCE/CE section uses these terms before explaining them. Peter Jackson (talk) 16:57, 10 October 2019 (UTC)

23.43695 + 66.33 = 89.76695. Offhand, I can't think of any reason why they shouldn't add up to 90. Maybe they're from sources with different dates, as the inclination does vary slightly over time. Peter Jackson (talk) 17:04, 10 October 2019 (UTC)

Egyptian calendar:

  1. I think, without checking right now, that Censorinus' calculations were out by 4 years
  2. 1460 years before 139 is 1322, not 1321
  3. all these calculations are based on the Julian year, not the astronomical year
  4. heliacal rising of Sothis occurs on a particular day 4 years running; what basis could we have for choosing 1 in particular?
  5. what basis could we have for saying the calendar was originally supposed to start at that time, rather than this being a later idea?
