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

Scotland didn't adopt the Gregorian calendar in 1599, it only changed the start of the year. The paragraph needs more rewriting. Peter Jackson (talk) 17:20, 10 October 2019 (UTC)
"35 years later"? That makes 1787. You can have either 1776 (Declaration of Independence) or 1783, when we recognized it. Peter Jackson (talk) 17:24, 10 October 2019 (UTC)
- The operative date is 17 September 1787, when the US Constitution was formally ratified. You can use 4 July 1776 if you prefer that but the wording will need to be changed. John (talk) 22:22, 10 October 2019 (UTC)
- Hadn't thought of that interpretation. But what you say isn't correct: that was the date of signing. It was ratified by the requisite 9 states (as specified in Article VII) on 21 June 1788. Well, that's less than 36 years from September 1752, so the statement might stand in that sense, though a source cited by WP says it didn't come into force till 4 March 1789.
