I was going to look that up to confirm it, but then I realized I could prove that statement true using some simple logic I already know.
Earth does one cycle around the sun in 365 days.
So at midnight looking straight up on a specific star (that is angled perpendicular of the rotating poles of earth) in the sky, the star you would have spotted on that day would appear slightly off the next day at midnight.
It would only end up on the same spot on midnight after 365 days.
So we are 5 days off, but I am going to believe it is true until someone is correcting me.
- unclad5968 4y agoWikipedia agrees with you, technically, except the theory specifically names the sun as the star used. However, the reference is a wolfram alpha article, which only references the book The Elements of Typographic Style. I've never read the book but using the sun position makes sense to me, so I will also choose to believe this until corrected.
