On December 6, 2022 There Will Be A Time of “GLOBAL DARKNESS”
The largest possible percentage of the human population on Earth will experience a moment of Global Darkness next Tuesday, December 6th at 19:56 UTC.
At that moment, the sky will be completely dark for about 85.92% of the world’s population , according to the specialized website Time and Date.
But how can it be night for almost everyone?
The reason is that the most populated areas of the world will be on the night side of the Earth at that time. This includes almost all of Asia, which is home to around 60% of all humans. Meanwhile the Americas, New Zealand and most of Australia will be bathed in sunlight – that although they are huge land masses relatively few people live there (North and South America together make up only about 13% of the population worldwide).
And Here Also It’s Worth Asking Why Night Affects More People On December 6th Than Say On December 5th?
Well it all depends on how well the shape of the affected region overlaps at night and twilight with the most populated regions of the world. This shape changes very slightly from day to day as the sun moves south before the December solstice and north again after the solstice.

Likewise although it is night for most people on December 6th it could be argued that December 21st and December 27th are alternate times of maximum darkness if we do not define night in strict terms, i.e. the sun must be at least 18 degrees below the horizon.
If the angle is less than 18 degrees it is twilight. This is the time in the morning and afternoon when indirect sunlight illuminates the sky to some extent.
“The dates we found just match the contours of the world’s population centers a little better than the day before or after,” explained science journalist Konstantin Bikos. “We were not particularly surprised that all dates fall in the northern winter. Most people live north of the equator and December is the month when the least amount of sunlight reaches the Northern Hemisphere.”
But it should be clarified that the difference is very small. Case in point: according to the calculations, the number of people who will experience the night at 19:56 UTC on December 6th is 6,665,450,571; exactly 24 hours earlier, it is 6,665,326,866. That’s a difference of 123,705 people, a small margin on a global scale.
“While we rely on our calculations and datasets, determining how many people are staying overnight at any given time is a pretty tricky business,” Bikos wrote. “On the one hand, the world’s population is not static. It changes over time and in some places it changes at a different pace than in others. We based our calculations on the last reliable population data we could find, but this is from 2020.”
“Besides, the margins are tiny. While our algorithms have identified a specific time when most people experience nighttime, they have also given us many other dates and times during the Northern Hemisphere winter with a nighttime population that is only a small fraction smaller. We are talking about a few tens of thousands of people, ”she concluded.
