Pacific/Port Moresby: Time Zone Guide for Papua New Guinea
Pacific/Port Moresby is the IANA time zone identifier for Papua New Guinea (PNG), anchored on its capital city. It operates on a fixed offset of UTC+10:00 year-round, with no daylight saving adjustments. This zone covers the entire country, including all islands and provinces, making it one of the few time zones that aligns a whole nation to a single constant offset.
Where Pacific/Port Moresby Applies
Pacific/Port Moresby is the sole official time zone for Papua New Guinea, an independent country in the southwestern Pacific. It covers all of PNG's mainland (the eastern half of New Guinea) and its numerous islands, such as New Britain, New Ireland, Bougainville, and the Milne Bay archipelago. The zone is named after Port Moresby, the capital and largest city, located on the southern coast. No other country uses this zone; it is unique to PNG.
Offset and Abbreviation
The standard offset is UTC+10:00, meaning local time is ten hours ahead of Coordinated Universal Time. The common abbreviation is PGT (Papua New Guinea Time). Unlike some zones that switch between standard and daylight time, PGT remains constant all year. This offset places Port Moresby in the same hour as Vladivostok (Russia), Brisbane (Australia), Guam, and Chuuk (Micronesia), but note that some of those locations observe daylight saving, creating temporary differences.
No Daylight Saving Time
Papua New Guinea does not observe daylight saving time. The country is near the equator (latitude 0-12°S), so day length varies little throughout the year. Sunrise and sunset times shift by only a few minutes seasonally, making DST unnecessary. As a result, Pacific/Port Moresby has a constant offset of UTC+10:00 every day of the year. There are no spring-forward or fall-back events, and the zone's rhythm is flat and predictable.
Main Countries and Cities
- Papua New Guinea: Entire country, including Port Moresby (capital), Lae, Mount Hagen, Madang, Kokopo, and Arawa.

Business Hours and Scheduling
Pacific/Port Moresby's business day (typically 9:00 AM to 5:00 PM PGT) overlaps well with East Asia and Australia. For example, when it is 9:00 AM in Port Moresby, it is 8:00 AM in Tokyo (JST, UTC+9) and 9:00 AM in Brisbane (AEST, UTC+10). For North America, the overlap is limited: 9:00 AM PGT is 6:00 PM EST (previous day) or 3:00 PM PST (previous day), so best to call early in PNG's morning. For Europe, 9:00 AM PGT is 1:00 AM CET (winter) or 2:00 AM CEST (summer) – a poor overlap; late afternoon in PNG (4:00 PM) aligns with early morning in Europe (6:00 AM CET). Always confirm if the other party uses DST, as that can shift the difference by an hour.
