Philippine Standard Time (Filipino: Pamantayang Oras ng Pilipinas, abbreviated PST), also known as Philippine Time (PHT) and informally Juan Time, is the official name for the time in the Philippines. The country only uses one time zone (UTC+08:00), and for a short period also used daylight saving time as an emergency measure.

Geographic details[edit]

Geographically, the Philippines lies within 116°40′ and 126°34′ east of the Prime Meridian, and is physically located within the UTC+08:00 time zone. Philippine Standard Time is maintained by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The Philippines shares the same time zone with Hong Kong, Macau, Singapore, most parts of China, Taiwan, Malaysia, Brunei, central Indonesia, and Western Australia.


Philippine Standard Time was instituted through Batas Pambansa Blg. 8 (that defined the metric system), approved on 2 December 1978 and implemented on 1 January 1983. The Philippines is one of the few countries to officially and almost exclusively use the 12-hour clock in non-military situations.

Use of daylight saving time[edit]

Due to frequent rolling blackouts, daylight saving time was instituted in the 1990s. As national power supplies and transmission systems recovered, daylight saving time was abolished.[1][2]

Juan Time[edit]

Television and radio stations in the Philippines display the time, but varied from a few seconds to minutes. In September 2011, the Department of Science and Technology proposed to synchronise time nationwide in an effort to discourage tardiness. PAGASA installed a rubidium atomic clock, a GPS receiver, a time interval counter, distribution amplifier and a computer to help calculate the time difference with every satellite within its antenna’s field of view.[3]

On May 15, 2013, President Benigno Aquino III signed Republic Act No. 10535, better known as the "The Philippine Standard Time (PST) Act of 2013" as a last step to finally implement the Juan Time. Effective June 1, 2013, all government offices and media networks will be required to use Philippine Standard Time as a basis to set their timepieces.[4][5]

IANA time zone database[edit]

The IANA time zone database contains one zone for the Philippines in the file, named Asia/Manila.
