Know the reason: Why is the longest day of the year on 21 June?
The longest day of the year on 21 June is the eggs of the Earth on its axis and its orbit around the Sun:
1. Earth’s inclination: Our Earth is bent about 23.5 degrees on its axis. This inclination is the main reason for changes in seasons.
2. Maximum inclination towards the sun: When the Earth revolves around the Sun in its orbit, around 21 June, the northern hemisphere is the most tilted towards the Sun.
3. straight rays on the Tropic of Cancer: At this time the rays of the sun fall straight on the Tropic of Cancer, which also passes through the middle of India. In this situation the sun rises quickly and sinks late, causing the day to become long and the night shortened.
4. Sunlight for more time: Due to this maximum inclination, sunlight in the northern hemisphere persists for the longest time on Earth (from about 15 to 16 hours, which depends on the latitude of the location). This is the reason that on 21 June, the day is the biggest and night is the youngest.
In contrast, June 21 is the shortest day and longest night in the Southern Hemisphere, as it is tilted away from the Sun. Then the situation overturns in December, when the longest day in the Southern Hemisphere and the shortest day (winter solstice) in the northern hemisphere.Also Read: 21 June History of Yoga Day, Learn what we learn from the theme of 2025
