Flat Earth Math | December Solstice Flat Earth / Globe Earth Azimuth predictions! (Armchair) @FlatEarthMath | Uploaded December 2023 | Updated October 2024, 6 hours ago.
Take a look over my shoulder as I pick two random world cities (one Northern Hemisphere, one Southern), and use SunCalc to get sunrise/sunset data from them. Let's see if my "Azimuth of Sunrise/Sunset" spreadsheet can correctly predict the real-world azumuths!

Featuring geometry based on Flat Earth (Gleason) and Globe Earth specifications, derived from scratch here, in this 18 minute video:
