Today is Winter Solstice. That is, the shortest day of the year. Last year, Winter Solstice took place on 22 December. But, this time it is on 21 December. Earlier in 2017, Winter Solstice was held on 21 December.

After all, why are these days big and small? Can any day except December 21 and 22 be the shortest day of the year? What does solstice mean and what is it? Does it have any effect on the weather? Let’s know …

Why are the days short and big?

  • This is because the earth is tilted. Actually, not only the Earth, but every planet in the solar system is tilted at different angles. Our earth is also tilted 23.5 degrees on its axis. Factors such as the earth tilting on its axis, rotating on its own axis, the time of sun rays falling in one place are different on different days of the year.

So will today be the shortest day of the year in the whole world?

  • It’s not like this. Today is the shortest day of the year in countries with the North Hemisphere (Northern Hemisphere). At the same time, today is the biggest day of the year in countries with South Hemisphere (Southern Hemisphere). This is the reason that today is the biggest day of the year in countries like Australia, New Zealand and South Africa.
  • The North Hemisphere is inclined towards the sun six months of the year. This brings direct sunlight to this hemisphere. During this time there is a summer season in the areas of North Hemisphere. For the remaining six months this area goes away from the sun and the days start getting shorter.

Will the length and timing of the shortest day of the year be the same?

  • Today is the shortest day of the year in different cities, but its length will vary. Like, the sun will rise in Delhi at 7:10 am today and it will be sunset at 5:29 pm. That is, the length of the whole day is 10 hours 19 minutes. At the same time, sun will rise in Bhopal at 6:58 am and sunset at 5:40 in the evening. That is, the length of the entire day will be 10 hours 42 minutes.
  • Now, a day before, that is December 20, the sun rose at 7:09 am in Delhi and sunset at 5:29 pm. That is, the total length of the day was one hour more than today, 10 hours 20 minutes. At the same time, on Sunday, December 22, the sun will rise at 7:10 am and sunset at 5:30 pm. That is, tomorrow also the length of the day will be one minute more than today.

Why does winter solstice date change? Does the month also change?

  • One year of Earth is completed in 365.25 days. That is, every year when the rays of the sun come to the earth for the shortest time, that time shifts about six hours. For this reason, every year there is a leap year. Which adjusts this time. That is, last year the sun had been on earth for the shortest time on 22 December, this year it became only on 21 December.
  • Winter solstice falls on any one of 20, 21, 22 or 23 December due to one year of earth and adjustment from leap year. However, it mostly falls on 21 and 22 December. Saying, the date of winter solstice changes, but the month never changes.
  • Similarly, the summer solstice, the longest day of the year, falls between 20 and 23 June. At the same time, the day and night are equal on 21 March and 23 September. It is called Equator. That is, on this day the sun is just above the Earth’s equator.

Does it have any effect on the weather?
Winter solstice causes winter to rise. From today, the beginning of winter in North Hemisphere and the beginning of summer in South Hemisphere is considered.
