Time in Palau is given by Palau Time (PWT;).[1] [2] Palau does not have an associated daylight saving time.[3]
Palau Time is equivalent to Japan Standard Time, Korean Standard Time, Pyongyang Time (North Korea), Eastern Indonesia Standard Time, East-Timorese Standard Time, and Yakutsk Time (Russia).
Until the end of 1844, Palau belonged to Captaincy General of the Philippines, which followed the date of the western hemisphere on its island. At the end of Monday, 30 December 1844, Palau was transferred to eastern hemisphere in response to Philippines's decision to switch sides of the line. This brought Palau closer to Asia (and in the process removing Tuesday, 31 December 1844 from the calendar).
Before time zones were introduced, every place used local observation of the sun to set its clocks, which meant that every location used a different local mean time based on its longitude. For example, Koror, the largest city of Palau at the time, at longitude 134°29′E, had a local time equivalent to GMT-15:02:04 under the date of the western hemisphere and GMT+08:57:56 under the eastern hemisphere.
In 1901, "Palau Time" (PWT) was established as GMT+09:00.
The IANA time zone database gives Palau one time zone, Pacific/Palau.[4]
