EASST — Easter Island Summer Time

How to Convert EASST to Other Time Zones
Open the EASST converter page: Go to https://www.xconvert.com/time-converter/easst-time-zone to open the visual comparison tool with Easter Island Summer Time (EASST) as the reference row. This page is useful when you need to line up schedules involving Easter Island, Chile, such as tourism bookings, flight planning through Santiago, or coordinating with teams that need to know the island’s summer clock at UTC-5.
Add comparison cities with the + Add City button: Click “+ Add City” and search for cities that commonly connect with Easter Island operations, such as Santiago, New York, and Los Angeles. This helps with real use cases like matching Easter Island hotel check-in coordination with mainland Chile, checking whether a customer support team in North America is online, or comparing island time with aviation and travel hubs.
Drag across the grid to select a meeting window: Click “Select” if needed, then drag across the EASST row to highlight a time range in purple, such as 9:00 AM to 11:00 AM EASST. Because EASST is UTC-5, that same window is 10:00 AM to 12:00 PM in Santiago during Chile Summer Time (UTC-4) and 2:00 PM to 4:00 PM in London during GMT, which makes it easier to see whether a morning call from Easter Island fits mainland business hours or European afternoon availability.
Export the selected time range: After selecting a range, use the export options shown by the tool: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. For example, a tour operator can send an ICS file so partners see the event in their own local calendars automatically, while a share link is useful for confirming a flight transfer window or remote handoff without re-explaining the time difference.
About Easter Island Summer Time (EASST)
EASST stands for Easter Island Summer Time, the daylight saving time observed on Easter Island (Rapa Nui), a special territory of Chile in the southeastern Pacific Ocean. Its exact standard relationship to Coordinated Universal Time during the summer period is UTC-5, meaning local clocks on Easter Island are 5 hours behind UTC.
EASST is used specifically for Easter Island and Salas y Gómez Island, not for mainland Chile. While mainland Chile uses its own seasonal time rules and offsets, Easter Island follows a separate island-based clock system that is typically 1 hour behind mainland Chile’s summer time, which is important for airline timetables, tourism operators, and government coordination.
When it is 12:00 PM (noon) in EASST, it is 5:00 PM UTC. That also means EASST is the same numeric offset as several other abbreviations listed at UTC-5, including COT, PET, and some uses of EST, but those abbreviations refer to different regions and may not follow the same daylight saving rules, so the city or region always matters more than the abbreviation alone.
Although Easter Island has a small population compared with major world time zones, its time is operationally important because the island is a major tourism destination, especially for travelers arriving via Santiago de Chile. Accurate conversion matters for hotel arrivals, guided excursions to archaeological sites such as Rano Raraku and Ahu Tongariki, and flight schedules that can cross date boundaries depending on the traveler’s origin.
EASST and Daylight Saving Time
EASST is itself the daylight saving time version of Easter Island’s local clock. During this period, Easter Island operates at UTC-5, and when daylight saving ends, it switches back to EAST — Easter Island Standard Time — at UTC-6.
For the current year, 2026, Easter Island switches to EASST on Saturday, September 5, 2026, when clocks move forward by 1 hour, and it switches back to EAST on Saturday, April 4, 2026, when clocks move back by 1 hour. These dates are especially relevant for travelers and distributed teams because a meeting that works one week may shift by an hour relative to New York, London, or Santiago after the transition.
This seasonal change affects practical planning. For example, during EASST at UTC-5, 9:00 AM on Easter Island is 2:00 PM UTC; after the return to EAST (UTC-6), that same 9:00 AM local time becomes 3:00 PM UTC. If you are scheduling airport pickups, cruise logistics, or remote support coverage, checking the exact date in the converter avoids one-hour errors during transition weeks.
Because Easter Island is in the Southern Hemisphere, its daylight saving season runs opposite to the pattern many users expect in Europe or North America. The summer clock generally begins around September and ends around April, which means businesses comparing EASST with US or UK time need to watch for periods when both regions are changing clocks on different dates.
Frequently Asked Questions
What does EASST stand for?
EASST stands for Easter Island Summer Time. It is the daylight saving time used on Easter Island (Rapa Nui), Chile, and its offset is UTC-5, meaning the local time is 5 hours behind Coordinated Universal Time during the summer season.
Is EASST the same as GMT?
No, EASST is not the same as GMT. GMT is UTC+0, while EASST is UTC-5, so Easter Island Summer Time is 5 hours behind GMT; for example, when it is 3:00 PM GMT, it is 10:00 AM EASST.
Which cities use EASST?
EASST is associated with Hanga Roa, the principal town on Easter Island, which is the main populated area using this time. Unlike larger time zones that cover many cities, EASST applies to a very limited territory, so most searches for cities using EASST are really asking about Easter Island / Rapa Nui itself.
What is the UTC offset for EASST?
The UTC offset for EASST is UTC-5. In practical terms, this means you subtract 5 hours from UTC to get local Easter Island summer time, so 18:00 UTC becomes 13:00 EASST.
When does EASST change?
In 2026, EASST changes back to standard time on April 4, 2026, when the island returns to EAST (UTC-6), and it resumes on September 5, 2026, when clocks move forward again to UTC-5. These transition dates matter for bookings, airline coordination, and international calls because the difference versus Santiago, New York, or London can shift by an hour.
Is EASST the same as EST or ET?
Not necessarily. EASST shares the UTC-5 offset with some uses of EST and ET during certain parts of the year, but those North American abbreviations depend on region and seasonal daylight saving rules, while EASST specifically refers to Easter Island Summer Time. Two zones can have the same offset on one date and still be different named time zones with different DST transition calendars.
Which country uses EASST?
EASST is used by Chile, specifically in its Pacific territory of Easter Island (Rapa Nui). It is not the time used by mainland Chilean cities such as Santiago, so travelers moving between Santiago and Easter Island should always verify the local offset before flights or hotel check-ins.
How far is EASST behind UTC?
EASST is 5 hours behind UTC. If a global team works from a UTC schedule, a 6:00 PM UTC handoff would occur at 1:00 PM on Easter Island during EASST, which is often useful for tourism operators, airport staff, and remote service teams supporting the island during local business hours.
