PAGASA said on Wednesday, June 20 that Filipinos will experience the longest daytime and shortest night of the year throughout the country on Thursday, same with other countries in the Northern Hemisphere.

In Metro Manila, the sun rose at 5:28 AM and the sunset is scheduled at 6:28 AM that will result in a total daylight of 13 hours approximately.

According to Encyclopaedia Britannica, the current event is caused by the ‘summer solstice’, or when the sun isĀ  “directly over the Tropic of Cancer.”

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,” PAGASA said.

PAGASA also said that it also marksĀ the start of the apparent southward movement of the sun in the ecliptic.
