Current Time in Pacific/Yap Time Zone

Overview and Geographic Scope

Pacific/Yap applies to the island of Yap and its surrounding atolls in the western Pacific Ocean. Yap is one of the four states of the Federated States of Micronesia (FSM). The zone covers the entire state, including the main islands of Yap Proper and the outer islands. The population is approximately 11,000. The offset is UTC+10:00, meaning local time is ten hours ahead of Coordinated Universal Time. The abbreviation for this zone is +10 (or CHST in some contexts, but locally it is simply Yap Time).

Offset and Abbreviation

The standard offset is UTC+10:00. There is no daylight saving time, so the offset remains constant throughout the year. The abbreviation used in the IANA database is +10, but locally the time is often referred to as Yap Time (YT). The zone is identical to Chamorro Standard Time (CHST) used in Guam and the Northern Mariana Islands, but Pacific/Yap is the designated IANA identifier.

Daylight Saving Time Behavior

Pacific/Yap does not observe daylight saving time. The offset is fixed at UTC+10:00 all year. This means there is no spring-forward or fall-back adjustment. The length of daylight varies slightly due to Yap's latitude (9.5°N), but the time remains constant. This simplifies scheduling for residents and avoids the biannual clock changes common in other regions.

Countries and Cities

The primary location is Yap, the capital of Yap State. The main city is Colonia, the administrative and commercial center. Other populated areas include the villages of Gagil, Tomil, and Weloy. The zone covers the entire Yap State, including outer islands like Ulithi, Woleai, and Ifalik. No other countries use Pacific/Yap; it is unique to Yap. Other zones at the same offset include Pacific/Guam, Pacific/Saipan, Australia/Brisbane, and Pacific/Port Moresby, but these are separate IANA entries.

Practical Guidance for Business and Scheduling

Yap's time zone (UTC+10:00) overlaps with business hours in parts of Asia and Oceania. For example, when it is 9:00 AM in Yap, it is 9:00 AM in Guam and Saipan, 8:00 AM in Tokyo (Japan Standard Time, UTC+9), and 7:00 AM in Beijing (China Standard Time, UTC+8). In the United States, when it is 9:00 AM in Yap, it is 6:00 PM the previous day in New York (Eastern Standard Time, UTC-5) and 3:00 PM the previous day in Los Angeles (Pacific Standard Time, UTC-8). For calls with Europe, 9:00 AM in Yap is 1:00 AM in London (GMT, UTC+0) and 2:00 AM in Berlin (Central European Time, UTC+1). The lack of daylight saving means these offsets remain constant, making it easier to plan recurring meetings. Best overlap hours for US West Coast are late afternoon Yap time (e.g., 5:00 PM Yap = 11:00 PM PST) or early morning Yap time (e.g., 7:00 AM Yap = 1:00 PM PST). For East Coast, 8:00 AM Yap = 6:00 PM EST. For Australia East Coast (AEST, UTC+10), times are identical, so Yap and Brisbane are always in sync.

History and Background

Yap has historically used UTC+10:00 as its standard time. The IANA time zone database includes Pacific/Yap as a canonical zone. It was created to represent the time observed on Yap Island. The zone does not have a history of daylight saving changes. The offset was likely chosen due to Yap's geographic location and colonial history under German and Japanese administrations, which used similar offsets. Today, Yap maintains the same time as Guam, which is a major regional hub.

Technical Details

The IANA identifier is Pacific/Yap. The zone is part of the Pacific region. The UTC offset is +10:00. The DST offset is also +10:00 (none). The abbreviation for standard time is +10. The zone's coordinates are approximately 9.5°N, 138.1°E. The country is FM (Federated States of Micronesia). The zone is equivalent to Etc/GMT-10 (though Etc zones have reversed signs).
