Summer, sun, good mood: When the warm season presents itself like this, you can’t have enough of it. It’s a good thing that today there is particularly long daylight available for this.

On June 21, the sun rises to the peak of its annual path. At exactly 11:14 a.m., the sun will be vertically above the Tropic of Cancer. The astronomical event is also the beginning of the calendar summer and the longest day of the year. In Berlin, for example, the sun rises at 4.44 a.m. on this day and only sets again at 9.31 p.m. That means: The day is 16 hours and 47 minutes long.

Even though the days are getting shorter and the nights longer from today, that’s no reason for melancholy, because this process happens very gradually. If you continue to look at the calculations for sunrise and sunset using the example of Berlin, you quickly see that the days on June 22nd and 23rd are also given as 16 hours and 47 minutes. Only from June 24th is the day one minute shorter. The sun then rises one minute later on this day than on the twelve previous days.

Overall, there is very little change in day length in June. On June 1st the day in Berlin was 16:27 hours long, on June 30th it was still 16:43 hours.

All sunrise and sunset values ​​are the results of astronomical calculations using the longitude, latitude and time zone of the location. The information is only provided to the minute for the general public. The shifts in sunrise and sunset occur at the same place around the summer solstice, initially with differences of seconds.

The solstice, which is known in technical jargon as the solstice (lat: standstill of the sun), also occurs at the same time in the southern hemisphere. If it is summer solstice in the northern hemisphere, then winter solstice is in the southern hemisphere with the longest night of the year.

For meteorologists, summer begins on June 1st. The meteorological beginning of autumn is always on September 1st. The simple assignment of exactly three months per season should make data easier to compare. The astronomical summer ends this year, on the other hand, with the start of autumn on September 23 at 3:03 a.m. The astronomical event on this day is called the equinox. That means: The day will then be just as long as the following night.
