Although there are 24 hours in a day, but due to the rotation of the earth, there are some such days throughout the year in which the days are long and the nights are short or the days are short and the nights are long. Throughout the year there are some such festivals or rather there are some such days,
So let's know about these days in more detail as well as try to understand
why these days are different from other days? Why some days, days are long and
nights short and why some days, days are short and nights are long.
When is the longest day?
June 21, also known as Yoga Day, is the longest day of the year. Why is it
so? This question must be coming in your mind, so let's know the answer to this
question.
Everything that happens in this world is due to nature and nature has a big
hand behind the shortening of 1 or 2 days in a year. On June 21, the sun's rays
fall on the earth for 15 to 16 hours, it is mostly seen in the countries of the
Northern Hemisphere along with India.
21 June is the longest day in India as well as in the countries of the
Northern Hemisphere. On June 21, the Sun moves from the Northern Hemisphere to
the Tropic of Cancer, due to which its rays begin to accelerate towards the
Northern Hemisphere and continue to shine for a long time, which makes it
appear that the days are very long. This is the reason why 21st June is
considered as the longest day of the year.
What is the reason behind the shortening of day and night?
As we all know, our earth revolves around the sun. For this reason, the
Northern Hemisphere is in direct contact with the Sun between the months of
March to September, and in these few months, the rays of the Sun continue to
shine in the Northern Hemisphere. In the Northern Hemisphere, the maximum
amount of sunlight falls on the days of June 20, 21 and 22. For this reason,
these days the summer season is seen in the Northern Hemisphere.
In contrast, the Sun's rays shine the most on December 21, 22 and 23 in the
Southern Hemisphere, which is located opposite the Northern Hemisphere. This is
the reason that these days summer season is seen in the Southern Hemisphere and
winter season is seen in the Northern Hemisphere. When sunlight falls on the
Northern Hemisphere, the days are longer and the nights shorter in the Northern
Hemisphere. On the other hand, when the sunlight falls in the Southern
Hemisphere, the days are shorter and the nights longer in the Northern
Hemisphere.
Along with revolving around the Sun, the Earth itself rotates by tilting
23.50 degrees on its orbit, so the part of the Earth where the sunlight falls,
there is day and the part where there is no sunlight there is night. Happens.
As it is winter time, at this time the Sun is moving from the Southern
Hemisphere to the Northern Hemisphere.
At this time in the Southern Hemisphere summer weather is seen. This summer
and autumn cycle continues throughout the year and is due to the Earth's orbit
around the Sun. There are two days in a year when day and night are equal.
March 21 and September 23 have 12 hours of day and 12 hours of night.
This is the natural reason for the big day, but there are some days in a
year which people call by the name of big day. December 25 and January 1 are
known as Bada Days because on this day people go out with their families, have
picnics and share a lot of happiness. People celebrate these two days as a
festival.
