According to EarthSky, based on algorithms and data from the Earth Science Information Center at Columbia University, USA, the time of maximum darkness occurred at 19:56, UTC on December 6, 2022 (ie 2:56 a.m. on December 7, Vietnam time).
At that time, the sky will be completely dark with about 85.92% of the world's population. At that time, darkness will rule the three most populous continents on Earth: Asia, Africa and Europe (with very small exceptions).
At 7:56 p.m. on December 6, UTC time, like any other time, the Sun will light up half of the world, the other half will sink into darkness and those who live there will spend the night.
However, up to 85.92% of the world's population will be immersed in the darkness of December 6, because the most populous areas in the world will be in the dark half of the Earth at that time. At this time, almost all of Asia - home to about 60% of the population - will be in the dark.
Meanwhile, South America, New Zealand and most of Australia will see the sunlight. Although it is a large area of land, this area is relatively sparsely populated. North and South America together account for only about 13% of the global population.
Also in this December, in addition to June 6, humanity has 2 other memorable days, December 21 and 27.
At 9:44 p.m. on December 21, UTC (ie 4:44 a.m. on December 22, Vietnam time), most of the Earth was at dawn, which affected 88.14% of the world's population.
Meanwhile, at 10:39 p.m. on December 27, UTC (ie2,39 a.m. on December 28, Vietnam time) was the peak of darkness. At that time, 86.11% of the world's population will experience nighttime (85.23%) or daylight (0.88%).
