Today, June 21, will be literally a long day

MANILA, Philippines – At 6:21 pm Saturday, June 21, the Philippines and countries in the northern hemisphere are closest to the sun.

"Philippine nights are at their shortest and daytimes are at their longest" during this period called the summer solstice, weather bureau PAGASA said. 

It's the "time of year when there exists the largest difference between the hours of daytime and nighttime at certain latitudes," PAGASA explained.

The stretch in the length of daytime is due to half the globe directly facing the sun.

"This is the time when the Sun attains its greatest declination of +23.5 degrees and passes directly overhead at noon for all observers at latitude 23.5 degrees North, which is known as the Tropic of Cancer. This event marks the start of the apparent southward movement of the Sun in the ecliptic," PAGASA said.

On the other side of the world, countries will be experiencing their shortest day of the year or their winter solstice. – Rappler.com
