Sunlight
Tomorrow morning, July 8, at 11:15 UTC (7:15 AM EDT), 99% of the world’s population will get some sunlight.
Because of the Earth’s axis and position in orbit, most of the world’s populated areas will simultaneously be in daylight.
Note: ~3% of the world in this specified zone will not perceive it as daylight because it is technically faint astronomical twilight, the period in which the sun is between 12°-18° below the horizon in the morning and evening.
In actuality, there are approximately 60 days around the June Solstice (June 20th), from May 18 to July 17, when 99% of humans experience daylight/twilight for a few minutes; tomorrow is the peak.
The remaining ~1% (about 80 million people) not receiving any sunlight at 11:15 UTC on July 8, live mainly in Australia, New Zealand, parts of Southeast Asia (e.g., Indonesia, Papua New Guinea), and Antarctica. The night side of Earth centers over the southwestern Pacific at the time.
The reverse phenomenon occurs on December 21 at 12:00 UTC (7:00 AM EST), during the December Solstice. At that time, the major population centers in the Northern Hemisphere are on the Earth’s night side.
Where will you be in the AM: in the light or dark?
