Is 21st of June the longest day of the year?

Yes, June 21st is usually the longest day of the year in the Northern Hemisphere, and it marks the summer solstice. On this day, the Earth’s tilt causes the North Pole to lean closest to the Sun, resulting in the maximum daylight hours and the shortest night.

The Sun’s rays fall directly on the Tropic of Cancer, making the day feel brighter and longer in countries like India, the USA, and most of Europe. While the exact date may vary slightly between June 20th and 22nd, June 21st is most commonly observed as the longest day of the year.
