?21 June, marks the longest day every year in Pakistan with 15:06 hours of daylight. The sun will rise at 4:56 AM and will set?on 7:12 PM on this day.
Countries lying on the northern hemisphere of the globe will experience the longest day?of the year. This phenomenon is known as the summer solstice.
What is Summer Solstice?
It is known as the longest day of the year in the northern hemisphere. It takes place in June while in the southern hemisphere, it is known as winter solstice that happens usually in December for the North.
Unlike the summer solstice,?the winter solstice is the shortest day of the year.
The region below the equator, also known as the southern hemisphere, has its longest day in December which is usually 4 hours, 29 minutes, shorter than what we have here in the northern hemisphere.
Summer solstice can actually happen on June 20 or June 22, but that?s very rare. The next June 22 solstice is due in 2203, while the last one was in 1975.
Will the Day-hours be Shorter From Now On?
Yes, daylight hours will drop from today until December 21, after that they?ll start to get longer again till the next summer solstice.
So, from today the nights are going to become longer and days shorter.
Why Does it Occur?
Our Earth orbits around the sun on a tilted axis, which gets changed at an?angle slightly every single day. So between March and September, Earth?s northern hemisphere gets more exposure to direct sunlight over the course of a day. For rest of the year, the southern hemisphere gets more. It?s why we have seasons. So it occurs only because of earth?s tilt towards the sun, which hits its maximum at 23? 26?.
