(Inside Manila) On June 21, the Philippines and other countries in the Northern Hemisphere will experience the longest day of the year for the summer solstice.


According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), June 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. The state weather bureau said that during the summer solstice, the northern hemisphere is tilted toward the sun to its maximum extent. The event marks the start of the apparent southward movement of the sun in the ecliptic.


The nights in the country are at their shortest and daytimes are at their longest during the summer solstice, which will occur on June 21 at 6:07 p.m. (PST). According to www.timeanddate.com, the sun will rise at 5:28 a.m. and set at 6:27 p.m., making daytime last for 12 hours and 56 minutes on that same day.


However, contrary to popular belief, it does not necessarily mean that it will have the earliest sunrise. In fact, it already occurred the first of June, with the sun rising three minutes earlier than that of June 21st. The earliest sunrise happens a few days before the summer solstice, and the latest sunset occurs a few days after.


People also mistake the summer solstice to be the hottest day of the year and that the Earth is closest to the Sun—it is not. Solstice comes from the Latin words sol (Sun) and sister (to come to a stop or stand still), thus, solstice translates to “sun stands still”.


At the same time, the Southern Hemisphere will be experiencing the winter solstice, the shortest day of the year.
