What happens to the sunlight population numbers if we alter the clock by a few minutes?. ![]() Is July 8 the only date this happens? If there’s a peak on that date, around 17 days after the June solstice, shouldn’t there be another one 17 days before the solstice?.With Jjust around the corner, we decided to expand our focus, and also answer one or two of the questions that have come our way since last year: When do most people experience night? Looking at the Year as a Whole The only large landmasses on the night side are Australia, New Zealand, and parts of Southeast Asia and Antarctica. (That is if you count the 3 percent that experiences astronomical twilight, which is hardly discernible from nighttime.)Īt that moment, most populated areas are on the day side of Earth or in one of the twilight zones. And yet, our number crunchers confirmed it: 99% of the world’s population really do receive some degree of sunlight at 11:15 UTC on July 8 each year.
