ANAST — Anadyr Summer Time
See what ANAST means, its UTC+12 offset, DST role, and how to compare or convert it with other time zones.
How to Convert ANAST to Other Time Zones
Open the ANAST converter page: Go to https://www.xconvert.com/time-converter/anast-time-zone to load the visual comparison grid with Anadyr Summer Time (ANAST) as the reference row. This page is useful when you need to line up working hours in Russia’s far northeast with other markets, such as scheduling a shipping update across the Bering region or checking whether a support handoff overlaps with teams in Tokyo or Auckland.
Add comparison cities with the “+ Add City” button: Click + Add City and search for places that commonly interact with UTC+12 regions, such as Tokyo, Sydney, and Los Angeles. This is especially practical for logistics, fisheries, aviation routing, and remote operations, because ANAST is 3 hours ahead of Tokyo (UTC+9), 1 hour ahead of Sydney during Australian Eastern Standard Time (UTC+10), and 19 hours ahead of Los Angeles during Pacific Standard Time (UTC-8), so the grid quickly shows whether a same-day call is realistic.
Drag on the grid to select a meeting window: Click Select, then drag across the ANAST row from 9:00 AM to 11:00 AM to create a purple highlighted range; you can fine-tune it with the left and right handles or move the whole block by dragging the center. A 9:00–11:00 AM ANAST slot converts to 6:00–8:00 AM in Tokyo, 7:00–9:00 AM in Sydney (AEST), and 2:00–4:00 PM on the previous day in Los Angeles (PST), which immediately shows why ANAST morning meetings often work better with Asia-Pacific teams than with North America.
Export the selected time range: Once your purple selection is active, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. For example, a dispatcher or project manager can send the ICS file to partners in different countries so the event appears in each person’s local time automatically, while the Share link is useful for quick approval in chat before booking a cross-border call.
About Anadyr Summer Time (ANAST)
ANAST stands for Anadyr Summer Time, the daylight saving time designation historically associated with the Anadyr time zone in Russia’s far eastern region. Its exact offset is UTC+12:00, meaning local clock time is 12 hours ahead of Coordinated Universal Time; when it is 12:00 noon UTC, it is 12:00 midnight the next day in ANAST.
ANAST has been used in the Chukotka / Anadyr region of Russia, centered on the area around Anadyr, the administrative center of Chukotka Autonomous Okrug. Anadyr itself has a population of roughly 16,000 people and sits on the Bering Sea side of the Russian Far East, much closer in practical geography to the North Pacific and Alaska-facing transport sphere than to European Russia.
Because ANAST is UTC+12, it shares the same raw offset as several other abbreviations, including NZST, FJT, MHT, TVT, WAKT, and PETT, but those are not interchangeable in all contexts. The offset may match, yet the legal time zone rules, daylight saving policies, and seasonal transitions can differ, which matters for flight planning, calendar invitations, and compliance-sensitive scheduling.
In practical conversion terms, ANAST is 9 hours ahead of Central European Time (UTC+3 during Moscow-standard alignment is not CET; CET is UTC+1 in winter), 4 hours ahead of India Standard Time (UTC+5:30), and 17 hours ahead of Eastern Standard Time (UTC-5). That means when it is 9:00 AM in ANAST, it is 5:00 AM in Bangkok (UTC+7), 1:00 AM in Dubai (UTC+4), and 4:00 PM on the previous day in New York during EST.
ANAST and Daylight Saving Time
ANAST is a daylight saving time label, not a year-round standard offset name. Historically, it represented the summer-time version of the Anadyr zone, while the standard-time counterpart is ANAT (Anadyr Time); both are commonly associated with UTC+12 in modern reference data, but older timekeeping systems and historical Russian reforms created periods where naming and legal offsets changed.
For the current year, 2026, there is no active daylight saving clock change scheduled for Anadyr/Chukotka under current Russian time law. Russia abolished regular seasonal daylight saving changes in 2014, so in real-world modern scheduling, users should expect no spring-forward or fall-back transition date in 2026 for Anadyr, even though the abbreviation database may still mark ANAST as a DST-related label.
Historically, when daylight saving practices were in force, ANAST would switch seasonally relative to ANAT, but that pattern is no longer used operationally in today’s Russian civil time system. For business coordination, this means you should verify the actual city and date on the grid rather than relying only on the abbreviation, especially if you are comparing archived timestamps, legacy software labels, or historical transport records.
This distinction is important for industries that depend on exact timestamps, such as aviation operations, maritime logistics, satellite communications, and energy infrastructure monitoring. A one-hour misunderstanding around a historical DST label can affect crew reporting times, cargo cutoffs, or incident logs, so using the date picker on the converter page is the safest way to confirm whether a past or present ANAST reference maps to the expected local time.
Frequently Asked Questions
What does ANAST stand for?
ANAST stands for Anadyr Summer Time. It is the daylight saving-related abbreviation connected with the Anadyr time zone in Russia’s far northeast, and its listed offset is UTC+12:00, placing it 12 hours ahead of UTC.
Is ANAST the same as GMT?
No, ANAST is not the same as GMT. GMT is UTC+0, while ANAST is UTC+12, so ANAST is 12 hours ahead of GMT; for example, when it is 8:00 AM GMT, it is 8:00 PM ANAST on the same calendar day.
Which cities use ANAST?
ANAST is associated with the Anadyr region in Chukotka, Russia, with Anadyr being the principal city usually referenced for this time zone label. In modern usage, city-based tools often map the region directly through Anadyr, Chukotka, because that is the main administrative and transport hub for the area.
What is the UTC offset for ANAST?
The UTC offset for ANAST is UTC+12:00. This means local ANAST time is always calculated by adding 12 hours to UTC, so 3:30 PM UTC becomes 3:30 AM the next day in ANAST.
When does ANAST change?
For the current year 2026, there is no scheduled daylight saving transition in the Anadyr region under current Russian law. Although the abbreviation ANAST is historically a summer-time label, Russia no longer observes routine seasonal clock changes there, so users working with present-day times should not expect a spring or autumn switch.
Is ANAST the same as ANAT?
Not exactly. ANAST refers to Anadyr Summer Time, while ANAT refers to Anadyr Time, the standard designation for the same regional time zone family; in modern reference tables both may appear with UTC+12, but they represent different naming contexts, especially in historical data.
Which countries use ANAST?
ANAST is tied to Russia, specifically the far eastern Chukotka/Anadyr area. It is not a multi-country time zone abbreviation in the way that some UTC offsets are shared across several island nations, even though many other abbreviations also use the UTC+12 offset.
How far ahead is ANAST compared with New York or London?
ANAST is far ahead of both cities, but the exact difference depends on whether New York and London are on standard time or daylight saving time. As a concrete example, ANAST is 17 hours ahead of New York during EST (UTC-5) and 12 hours ahead of London during GMT (UTC+0), so 9:00 AM in ANAST is 4:00 PM the previous day in New York and 9:00 PM the previous day in London.
