Summer Solstice 2021: The longest day of the year is called Summer Solstice. This year the summer solstice will start on 21st June at 9:2 am. International Yoga Day is also celebrated on this day. On the day of the summer solstice, the sun reaches its highest point in the sky. Due to this, there is more light in the day and night is also late. This day is also the longest day of the year. The summer solstice is also known as the estival solstice or midsummer. Here we are telling you about 10 important facts related to the Summer Solstice.
10 important facts about summer solstice
1. Today is the longest day in the Northern Hemisphere, because the Sun is directly over the Northern Hemisphere. For this reason it is called summer solstice. At the same time, today is the shortest day in the Southern Hemisphere. For this reason it is also called winter solstice.
2. Sankranti occurs in the month of June and December. The first Sankranti of the year will be on 21st June. This is followed by the second Sankranti in December. In the summer solstice the Sun is just above the Tropic of Cancer and in the winter solstice the Sun is just above the Tropic of Capricorn.
3. The Sun reaches its northernmost position during the June solstice. During this time the Sun remains stationary on the Tropic of Cancer. It then reverses its direction and again starts moving towards south. On the other hand, the exact opposite happens during the December solstice. During this time the Sun reaches its southernmost position in the sky and gets fixed at the Tropic of Capricorn. Then it starts moving towards north direction.
4. The time of summer solstice is the same all over the world. Technically the June solstice is the exact moment when the Sun is directly over the Tropic of Cancer. In 2021, this will happen on June 21 at 03:32 UTC.
5. Most people consider June 21 as the date of the June solstice. However, it can happen anytime between June 20 and June 22. The solstice of June 22 is rare. The last time in 1975 was June Sankranti on 22 June.
6. Astronomers and scientists mark the beginning of summer in the Northern Hemisphere and winter in the Southern Hemisphere through the June solstice. In many Northern Hemisphere cultures, this day is traditionally considered the midpoint of the summer season. Midsummer celebrations are common in many European countries on or around the northern summer solstice.
7. Earth is farthest from the Sun during the June solstice. Earth’s distance from the Sun has little effect on the seasons. The seasons change here due to the tilt in the Earth’s axis of rotation. During the June solstice, the Northern Hemisphere is toward the Sun, making it hotter, while the Southern Hemisphere is tilted away from the Sun. That’s why it is winter here at this time.
8. The June solstice is the longest day of the year in the Northern Hemisphere, but most places do not see the first sunrise on this day. It takes place a few days before it, while sunset also does not happen later on this day, it happens a few days after it.
9. Even though the sun is right above our head on this day, this day is not even the hottest day of the year. The hottest day of the year in the Northern Hemisphere usually occurs a few weeks or sometimes a few months after the solstice. This is because it takes time for oceans and landmass to warm up.
10. The June solstice is the only day of the year when the Arctic Circle is not dark for 24 hours. As in the Northern Hemisphere, any location south of the Antarctic Circle has a polar night several days before the June solstice.
