Testing the Gleason Map Using Real Sunlight Data | Does It Actually Work?

Flat earthers claim the Gleason map is the real map of the Earth — a pure, distortion-free version of reality that NASA supposedly doesn't want you to see.
But what happens when we test that map using actual sunrise and sunset data, direct sun observations, and basic geometry? It falls apart — fast.

In this video, I use December 21st (the winter solstice) to compare Oulu, Finland and Cape Town, South Africa — two cities nearly aligned longitudinally, but in opposite hemispheres. Using verified data from dateandtime.com, I show the exact sunrise and sunset times for both cities and determine the geographic position (GP) of the sun at each moment.

Then, I plot those sun positions on the Gleason map — the flat Earth model that’s plastered across TikTok, Rumble, and YouTube. What we discover is hilarious and undeniable:

Finland only sees the sun when it’s near southern Africa…

Cape Town sees the sun even when it’s farther from the sun’s ground position.

On the Gleason map, this makes zero sense. On the globe? It lines up perfectly.

I also show a real-time video of Earth’s rotation, demonstrating why Cape Town gets 14+ hours of daylight while Finland barely sees the sun. This isn’t theoretical. This is visible reality — and it debunks the Gleason map with eyes-on-the-sun accuracy.
