Why is tomorrow going to be the shortest day of the year in India?

 

This year, the December Solstice, also known as Winter Solstice, falls in India on December 22, 2023. For some regions, it falls on December 21. The first day of astronomical spring in the Northern Hemisphere, the Winter Solstice can fall anytime from December 20 to 21. In rare cases, the winter solstice can fall on December 23. The last time the Winter Solstice fell on December 23 was in 1903. Winter Solstice 2023 falls at around 8:57 am IST on December 22.  Solstices occur twice a year. They mark the beginning of astronomical summer and winter. Solstices take place around June 21 and December 21.

The winter solstice will be observed in India on December 22 at 8:57 AM. The shortest day of the year will occur in the Northern Hemisphere during the day, with roughly 7 hours and 14 minutes of daylight. Then, on December 22, Earth’s axis will be designated as the one that is furthest from the sun. This indicates that compared to the summer solstice, the winter solstice’s day is 8 hours, 49 minutes shorter.

The word solstice is derived from the Latin word ‘solstitium’, which means ‘the Sun stands still’.

Here’s why the winter solstice brings the shortest day:

  • Earth’s tilt: Our planet isn’t straight up and down as it orbits the Sun. It’s tilted at an angle of 23.5 degrees. This tilt means that different parts of Earth receive direct sunlight at different times of the year.
  • December tilt: During December, the Northern Hemisphere is tilted furthest away from the Sun. This results in the sun staying below the horizon for a longer period, meaning fewer hours of daylight and making it the shortest day.
  • Southern Hemisphere flip: While the Northern Hemisphere experiences winter solstice, the Southern Hemisphere enjoys the summer solstice, meaning their longest day.

What is Solstice?

The Earth receives different amount of sunlight depending on the region and the time of the year. The Earth’s tilt makes one half of the world receive sunlight while the other half stays dark. The Earth’s axis tilts at 23.5 degrees because of which, one half of the world receives more sunlight and, hence, has a longer day time while the other half has a longer night.

When the tilt of the Earth is the most extreme with respect to the sun, one hemisphere has its longest day while the other hemisphere has the longest night. This phenomenon happens twice a year and it is known as solstice.

Why does Solstice occur?

Solstice takes place because of the Earth’s tilt. The Earth’s tilt makes sure that we have four different seasons. The sun-facing hemisphere experiences summer — June to August in the Northern hemisphere and December to February in the Southern hemisphere. The hemisphere that is away from the sun experiences winter.

During summer solstice in the Northern hemisphere, parts of the Arctic Circle experience 24 hours of daylight while in the Antarctic region, which is in the Southern hemisphere, there is no sunlight at all. The opposite takes place during winter solstice. The Arctic Circle gets no sunlight while the Antarctic belt gets sunlight for 24 hours.

When does Solstice occur?

Solstices occur twice a year. They mark the beginning of astronomical summer and winter. Solstices take place around June 21 and December 21. They do not occur on the same day every year because the astronomical year is 365.25 days long and we consider 365 or 366 days. Because of this reason, solstices can shift.

Solstices have been known to people for many centuries. They have inspired religious traditions throughout the world and many monuments have been built to mark the event.

In India, JN.1 was detected in Kerala on December 8, with a reported case in 79-year-old woman who experienced mild symptoms of Influenza like Illness (ILI). The country is urged to stay vigilant and implement necessary measures to contain the variant’s spread.

Preventive Measures of JN.1

Proactive preventive measures are crucial in curbing the spread of JN.1 Experts emphasize the following precautions:

  • Regular hand sanitization remains a cornerstone in preventing the transmission of the virus.
  • Wearing masks, especially high-quality masks, contributes significantly to reducing the spread of respiratory droplets.
  • Maintaining a safe distance from others remains an effective measure in preventing the spread of the virus.

Vaccination Against JN.1 and Other Variants

Despite the challenges posed by the evolving JN.1 subvariant, Kerkhove reassured the public that COVID-19 vaccines continue to provide protection against severe disease and death, even with the circulating variants, including JN.1. She urged individuals to get vaccinated when it is their turn and to employ various tools to protect themselves from infection.

WHO’s Call for Continued Surveillance and Sequence Sharing

On Sunday, December 17, the WHO emphasized the need for member states to maintain vigilance through continuous sequence sharing and robust surveillance efforts. The organization is closely monitoring the situation and assessing the impact of the JN.1 subvariant on the global landscape of respiratory diseases.

Insights from WHO’s COVID-19 Technical Lead

Maria Van Kerkhove, the COVID-19 technical lead at WHO, shared a video on social media platform X, explaining the factors contributing to the recent surge in respiratory infections. Kerkhove highlights that the holiday season has led to increased gatherings, especially in regions entering winter months. Poor ventilation in indoor settings provides an ideal environment for the efficient spread of various pathogens, including COVID-19, influenza, rhinovirus and mycoplasma pneumonia.
