CHUT — Chuuk Time
See what CHUT means, where it is used, its UTC+10 offset, and how to compare or convert it with other time zones.
How to Convert CHUT to Other Time Zones
Open the CHUT converter page: Go to https://www.xconvert.com/time-converter/chut-time-zone to load the visual comparison tool with Chuuk Time (CHUT, UTC+10) as the reference row. This page is useful when you need to line up working hours in Micronesia with partners in places like Sydney, Tokyo, or Honolulu for shipping coordination, travel planning, or remote operations across the Pacific.
Add comparison cities with the + Add City button: Click “+ Add City” and search for cities that commonly interact with the western Pacific region, such as Sydney for aviation and regional business, Tokyo for logistics and trade, or Honolulu for trans-Pacific travel coordination. Adding these rows lets you compare CHUT against other operational hubs visually, which is especially helpful because CHUT stays fixed at UTC+10 year-round while some comparison zones change seasonally.
Drag on the grid to select a meeting or travel window: Click “Select” if needed, then drag across the CHUT row on the 24-hour timeline to highlight a time block in purple; you can resize it with the left and right handles or move the whole block by dragging the center. For example, selecting 9:00 AM to 11:00 AM CHUT shows that it is 11:00 AM to 1:00 PM in Sydney during Australian Eastern Standard Time, but only 8:00 AM to 10:00 AM in Tokyo and 1:00 PM to 3:00 PM on the previous day in Honolulu, which helps confirm whether a same-day Pacific call is realistic.
Export the selected time range for real scheduling use: Once your purple selection is set, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially practical if you are sending a confirmed call slot to a distributed team, sharing a port operations handoff window, or creating a calendar event that each participant will see automatically in their own local time.
About Chuuk Time (CHUT)
CHUT stands for Chuuk Time, the standard time used in the State of Chuuk in the Federated States of Micronesia. Its exact offset is UTC+10:00, meaning local time in Chuuk is always 10 hours ahead of Coordinated Universal Time and 10 hours ahead of GMT in clock difference, although GMT and UTC are not technically identical standards.
Chuuk is part of Micronesia in the western Pacific Ocean, and CHUT is primarily associated with the Chuuk region, including the islands around Chuuk Lagoon, one of the best-known geographic features in the area. The Federated States of Micronesia uses multiple time zones across its states, so CHUT is specifically relevant when coordinating with Chuuk rather than assuming one single national time for the entire country.
Because CHUT is UTC+10, it matches the same raw offset as several other abbreviations at certain times of year, including AEST, AET, ChST, DDUT, K, PGT, VLAT, YAKST, and YAPT. However, equal UTC offset does not always mean the same legal time zone rules, because some of those regions may observe daylight saving time in some seasons or use different naming conventions tied to local law and geography.
In practical terms, CHUT is 1 hour behind Japan Standard Time (UTC+9)? No — with CHUT at UTC+10, it is actually 1 hour ahead of Japan Standard Time only if JST were UTC+9, but JST is UTC+9, so CHUT is 1 hour ahead of Tokyo. CHUT is also 10 hours ahead of London during GMT, 9 hours ahead of London during British Summer Time, and 15 hours ahead of New York during Eastern Standard Time or 14 hours ahead during Eastern Daylight Time, which matters for customer support windows and overnight coordination.
CHUT and Daylight Saving Time
Chuuk Time does not observe daylight saving time. The DST status for CHUT is false, which means it does not switch forward in spring, does not switch back in autumn, and remains at UTC+10:00 for all dates of the year.
For the current year, 2026, there are no DST transition dates for CHUT: it does not change in March, April, October, or November, and it does not switch to any alternate summer abbreviation. That makes CHUT easier to use for long-term planning than many North American, European, or Australian zones, because a meeting set for 10:00 AM CHUT every Tuesday stays at 10:00 AM CHUT all year even if the counterpart city shifts by an hour seasonally.
The main complication comes from the other time zone, not from Chuuk itself. For example, CHUT stays fixed while Sydney moves between AEST (UTC+10) and AEDT (UTC+11), so a call that lines up perfectly in July may be one hour off in December unless you recheck the date picker on the converter.
Frequently Asked Questions
What does CHUT stand for?
CHUT stands for Chuuk Time, the standard time used in the State of Chuuk in the Federated States of Micronesia. It is a fixed time zone with an offset of UTC+10:00, so local time there is always 10 hours ahead of UTC.
Is CHUT the same as GMT?
No, CHUT is not the same as GMT. GMT is UTC+0, while CHUT is UTC+10, so CHUT is 10 hours ahead of GMT at all times of year.
Which cities use CHUT?
CHUT is associated with the Chuuk region of the Federated States of Micronesia rather than a long list of major global metro areas. The most relevant populated area is around Weno and the Chuuk Lagoon area, which function as the main reference points when scheduling local time in Chuuk.
What is the UTC offset for CHUT?
The UTC offset for CHUT is +10:00. In other words, when it is 12:00 UTC, it is 22:00 in Chuuk Time on the same calendar day.
When does CHUT change?
CHUT does not change during the year. There is no daylight saving transition, no switch to a summer time abbreviation, and no scheduled clock change in 2026 or in a normal annual cycle.
Is CHUT the same as AEST?
CHUT shares the same UTC+10 offset as Australian Eastern Standard Time (AEST) during the part of the year when eastern Australia is on standard time. However, they are not the same legal zone in all contexts, because Australian regions may switch to AEDT (UTC+11) during daylight saving, while CHUT remains fixed at UTC+10.
How far ahead is CHUT from New York or London?
CHUT is 15 hours ahead of New York during Eastern Standard Time and 14 hours ahead during Eastern Daylight Time. It is 10 hours ahead of London during GMT and 9 hours ahead during British Summer Time, so a morning in Chuuk often corresponds to the previous evening or overnight period in North America and early morning in Europe.
Does CHUT ever switch to another abbreviation?
No, CHUT does not switch to a daylight saving abbreviation or seasonal variant. The zone remains Chuuk Time (CHUT) at UTC+10:00 throughout the year, which makes recurring scheduling more predictable than in regions with spring and autumn clock changes.
