I decided to look into how much daylight certain places have and I'm a little confused about something. Maybe someone can explain this.
I made a chart of the Sunlight hours for the USA on June 20th, 2018 when the sun would be at the Tropic of Cancer.
MAINE 15:53
MASS 15:17
NEW YORK 15:05
PENNSYLVANIA 15:01
DELAWARE 14:55
VIRGINIA 14:42
(Nags Head) NORTH CAROLINA 14:36
(Georgetown) SOUTH CAROLINA 14:22
GEORGIA 14:15
(Jacksonville) FLORIDA 14:06
(Melbourne) FLORIDA 13:56
(Miami) FLORIDA 13:45
I was confused as to why the hours of sunlight decrease the closer it gets to Florida. Florida is the closest to the Tropic of Cancer, right? During June-July-August reaching its peak June 20th. Is this because the sun is pretty much directly overhead so it leaves our eyesight and horizon quicker than those who live in Mass? A little confused by that. Curiously I decided to see how the hours work if we go directly to the left of Maine.
LEFT OF MAINE
New Hampshire 15:35 (Bangor)
Vermont 15:35 (Bakersfield)
Michigan 15:34
Wisconsin 15:33
South Dakota 15:33
Wyoming 15:33
Oregon 15:41 (Portland)
The hours of sunlight stays the same. Off by a minute or few depending on the city I chose. But they all stay within the 15:33 mark.
If the Gleason's map and maps like it are ... close to "accurate" as can be, it doesn't make sense. Why Alaska gets a 24 hour sun when it appears the sun is farthest from Alaska when it's circling above. Wouldn't Florida be getting the 24 hour sun since it's almost on top of the Tropic of Cancer? Otherwise, the map really is wrong and nothing is where it's suppose to be.
The higher you go (above Oregon), the hours of sunlight increase. (Bellingham) WASHINGTON 16.10. Fairbanks Alaska (lower end) gets 21.48 but Barrow Alaska (upper end) gets 24 hours.
I hope this makes sense.

If you look at Timeanddate.com's world day/night map for June 20, you can see why. Here's a link to June 20th at 9:00 UTC: https://www.timeanddate.com/worldclock/sunearth.html?month=6&day=20&year=2018&hour=9&min=0&sec=0&n=&ntxt=&earth=0
As you can see on the US's east cost, Maine and Massachusetts get hit with light first. Then, about an hour later, Florida gets light.
On June 21st, at ~1:50 UTC, Florida then experiences sunset. Around 2:30 UTC, MA and ME then get sunset.
When I get the chance I'll make a 3D model.

What is UTC?
I look forward to your model or a link showing me how this works. I'm really interested how the sun and moon work.

Coordinated Universal Time.

See the attached image for the orientation of the sun during the summer solstice (not to scale; for illustration only). Dawn sweeps from the NE during the solstice, and evening twilight from the SE, because the earth is tilted with the Tropic of Cancer "pointing" upward toward the sun. So, as the earth spins, the sun appears to circle in a cone above the globe, "peeking" over the north pole such that it doesn't appear to set for anyone inside the artic circle during the solstice. So, northern cities see an earlier sunrise and a later sunset than mid latitudes during the summer. Opposite situation in the winter. Mid-latitudes see less extremes in the length of the day, with equatorial locations having the least amount of difference between length of day throughout the year. But the difference between length of days between summer and winter become more and more extreme, the further away from the equator you get.
I snapped these from an animated gif once upon a time. You can probably find it online.

How would that look on the Circular flat map? Is there a picture or animation for that?
-
I don't know. Mine's a globe earth answer only. A flat earth proponent will have to tackle the flat earth perspective.
-
I'm surprised no one has done this... Considering the subject at hand. Aren't we suppose to be trying to figure this out?

This one is easy. The sun's area of light overlaps the North Pole when the Sun is at the Tropic of Cancer. This is why higher latitudes increase in daylight duration until, when far enough North, the sun ceases to set at all and the Midnight Sun occurs.

Not to be a pest but can you show me what you mean? Image or video?

I'd like to see that too. Those I've seen work okay on the north pole side of the equator, but when the sun is moving on paths between the equator and the tropic of Capricorn, they don't show daylight north of the equator the way we experience it (who sees sunrise earlier, how long daylight lasts, slant direction of the rising or setting sun, etc.)
I've tried to model it myself, mostly leveraging off other efforts, but haven't been able to figure out a solution.

Not exactly getting a great picture in my mind. Could we get a picture or a graphic?
