The abbreviation for Philippine Time is PHT. It refers to the UTC+08:00 time zone used throughout the Philippines, which has no daylight-saving clock changes today.
PHT stands for Philippine Time, while Philippine Standard Time is also commonly abbreviated PST or PhST. Because “PST” is also widely understood as Pacific Standard Time in North America, PHT is the clearer international abbreviation for the Philippines. The country uses one national time zone despite stretching across many islands.
The Philippines once had more complicated clock history. In 1844, Spanish colonial authorities moved the country across the International Date Line by deleting December 31 from the calendar, aligning the Philippines’ date with neighboring Asian territories. The country also briefly observed daylight saving time during several historical periods, but it has remained on UTC+08:00 since 1978.
PHT is shared in offset with places including China, Malaysia, Singapore, Hong Kong, Taiwan, and Western Australia. It is not the same as MYT, ICT, or PST, even when some of those abbreviations appear in international scheduling tools.
