It is no exaggeration to say that it was the summers above and below, with some soaring summers interspersed with truly disastrous weeks of weather.
As the night goes on, the days get longer and autumn is gradually approaching.
Here’s what you need to know about the two possible season start dates in the UK and the fall equinox:
When will the fall of 2021 begin?
The first day of autumn can be two different dates, depending on whether you use the definition of meteorology or astronomy.
The meteorological system is the simpler of the two. Based on the Gregorian calendar, divide the year into four seasons of three months. This makes it easy to compare seasonal and monthly statistics.
Therefore, every year, autumn lasts from September 1st to November 30th, and winter begins in early December.
In the meteorological calendar, spring always includes March to May, and summer lasts from the beginning of June to the end of August.
The astronomical season is not that simple, as it is based on the location of the autumn equinox that comes later in the moon and does not always have the same date.
As a result, autumn has a different start date than the meteorological system. This autumn equinox is Wednesday, September 22nd, with the earliest day being September 24th.
According to the system, autumn will change to winter on the day of the winter solstice, which is Tuesday, December 21st.
Astronomically speaking, this summer began on Monday, June 21, the day of the summer solstice.
What is the autumn equinox?
The equinox is named in Latin to mean “equal night” and indicates only two points in a year when the equator is the closest part to the Earth’s Sun.
Theoretically, this means that you should get 12 hours of sunlight and darkness that day anywhere on Earth, but this is slightly due to the Earth’s atmosphere, which affects the way we see sunlight. It gets complicated.
For six months each year, either the northern or southern hemisphere is slightly facing the sun, with warmer spring and summer temperatures.
The autumn and spring equinoxes indicate the points where the two hemispheres alternate, and the summer solstice and winter solstice indicate that the sun reaches the northernmost and southern points.
