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
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, China, Taiwan, Malaysia, Brunei, central Indonesia, Western Australia
Western Australia
and Irkutsk. History[edit] Philippine Standard Time
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.[citation needed][dubious – discuss] From 1521 to 1844, the Philippines
had the same date as Mexico, because it had been a Spanish colony supplied and controlled via Mexico until Mexico's independence in the 1820s. Monday, 30 December 1844 was immediately followed by Wednesday, 1 January 1845, which added 1 day or 24 hours to the local time. This meant that International Date Line
International Date Line
moved from going west of the Philippines
to go on the east side of the country.[3] At the time, local mean time was used to set clocks, meaning that every place used its own local time based on its longitude, because the time was measured by locally observing the sun. Time in the Philippines[edit]

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.[5][6] On May 15, 2013, President Benigno Aquino III
Benigno Aquino III
signed Republic Act No. 10535, better known as "The Philippine Standard Time
Philippine Standard Time
(PST) Act of 2013" as the latest step of implement the Juan Time. Since June 1, 2013, all government offices and media networks are required to synchronize their timepieces with PAGASA's rubidium atomic clock.[7][8] In addition, the first week of January will be regularly observed as the National Time Consciousness Week.
