When does summer begin and why does the hottest season get longer?

Must read

The summer solstice, or the beginning of astronomical summer, will occur June 21, 2023, 4:57 pm At this point, the Sun will be at the northernmost point of its path, entering the sign of Cancer, and our Northern Hemisphere will be most inclined towards the Sun. Thus, the summer solstice is the longest day in the Northern Hemisphere, which we enjoy for a full 16 hours and 23 minutes. Then the days start getting shorter again. Summer ends with the autumn equinox having a date of September 23, 2023.

The summer solstice occurs on June 20, 21, and in exceptional cases on June 22.

At the same time, the solstice can fall on the twentieth, twenty-first, and rarely even on the twenty-second of June. If we are based on Central European Summer Time, the summer solstice is in the first half of the 21st century. 41 times 21.06.. and nine times 6/20. The summer solstice occurred on June 20, 2020, for the first time since 1796, and will repeat in 2024, 2028, 2032, 2036, 2040, 2044, 2048 and 2049. As for the solstices June, 22are very rare – the last one happened in 1975, and the next one won’t happen until 2203.

Why does the date of the summer solstice change?

Because there are deviations between the astronomical calendar and our regular calendar, the date of the summer solstice does not always fall on the same day. The calendar year is 365 days long, but the Earth revolves around the Sun in 365 days, 5 hours and 49 minutes. Therefore, the moment of the summer solstice each subsequent year is pushed back by these 5 hours and 49 minutes. All this together including leap year, when the summer solstice “jumps” back again, and at the same time the date can change to June 20.

Summer will become longer and longer – until the year 4000!

Other differences also arise from changes in the Earth’s orbit. Warm weather lovers will certainly be pleased that summer is currently the longest of all seasons and is getting longer, but this process is really very slow. By the year 3000, summer will be 6 hours and 29 minutes longer, and in the year 4000, summer will be longer than today’s by 6 hours and 43 minutes longer. Then it starts to shorten again.
