How to Convert AZST to Other Time Zones
Open the AZST converter page: Visit https://www.xconvert.com/time-converter/azst-time-zone to load the visual comparison grid with Azerbaijan Summer Time (AZST) already shown at UTC+5. This page is useful when you need to line up work with contacts in Azerbaijan, check whether a support shift overlaps with Europe or Asia, or confirm the local time for travel and logistics connected to Baku.
Add comparison cities: Click + Add City and search for cities that commonly interact with Azerbaijan, such as London for energy and finance, Dubai for regional trade and aviation, or Karachi because Pakistan also runs on UTC+5 year-round. Adding these rows lets you compare AZST against markets and business hubs that often matter for oil and gas, shipping across the Caspian region, and remote team scheduling.
Select a time range on the grid: Click Select, then drag across the AZST row to highlight a working window such as 9:00 AM to 11:00 AM AZST. That selection shows, for example, 5:00 AM to 7:00 AM in London during standard time, 8:00 AM to 10:00 AM in Dubai, and 9:00 AM to 11:00 AM in Karachi, which quickly tells you whether a Baku morning meeting is practical for Gulf partners but too early for Western Europe.
Export and share the result: After selecting the purple time block, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially helpful when sending a meeting slot to a distributed team, creating a calendar invite that automatically converts from AZST into each attendee’s local time, or sharing a link with travel coordinators and operations staff.
About Azerbaijan Summer Time (AZST)
AZST stands for Azerbaijan Summer Time, the daylight saving time designation historically used for Azerbaijan when clocks were moved one hour ahead of standard time. Its exact offset is UTC+5:00, meaning local time in AZST is 5 hours ahead of Coordinated Universal Time and 1 hour ahead of Azerbaijan Time (AZT), which is UTC+4:00.
AZST is associated with Azerbaijan, a South Caucasus country located between the Caspian Sea, Russia, Georgia, Armenia, and Iran. The country’s capital, Baku, is the main economic and transport center, with a population of over 2 million in the metropolitan area, and it has historically been the principal city tied to Azerbaijan’s official time observance. In practical scheduling terms, when it is 12:00 noon UTC, it is 5:00 PM in AZST.
AZST shares the same UTC+5 offset with several other abbreviations, including PKT (Pakistan Standard Time), UZT (Uzbekistan Time), TJT (Tajikistan Time), TMT (Turkmenistan Time), MVT (Maldives Time), YEKT (Yekaterinburg Time), AQTT, ORAT, MAWT, TFT, AMST, and E in their respective regional contexts. Even though these zones have the same numerical offset at certain times, they are not interchangeable in every calendar system because the abbreviation, region, and daylight saving rules can differ.
AZST and Daylight Saving Time
Azerbaijan Summer Time is the daylight saving version of Azerbaijan’s clock, shifting from AZT (UTC+4) to AZST (UTC+5) when DST is in effect. Under the historical DST pattern used in Azerbaijan, clocks moved forward by 1 hour in spring and returned back by 1 hour in autumn, so a local 8:00 AM standard-time schedule became 9:00 AM under summer time relative to UTC.
For the current year, 2026, if Azerbaijan were observing the historical DST system, the switch to AZST would typically occur on Sunday, March 29, 2026, and the switch back to AZT (UTC+4) would occur on Sunday, October 25, 2026, matching the common last-Sunday-in-March and last-Sunday-in-October pattern used in many post-Soviet and European-adjacent systems. On the spring transition, clocks would jump from 4:00 AM to 5:00 AM local time, and on the autumn transition, clocks would move back from 5:00 AM to 4:00 AM local time.
However, users should know the real-world policy context: Azerbaijan abolished seasonal daylight saving time in 2016 and has remained on AZT (UTC+4) year-round since then. That means AZST is mainly a historical or legacy abbreviation that may still appear in old datasets, archived schedules, software time libraries, or older travel and enterprise systems, but it is not part of Azerbaijan’s current civil timekeeping practice.
Comparing AZST with Other Major Time Zones
Because AZST is UTC+5, it is 1 hour ahead of Gulf Standard Time in Dubai (UTC+4), the same as Pakistan Standard Time in Karachi (UTC+5), and usually 4 to 5 hours ahead of London depending on whether the UK is on GMT or BST. For example, when it is 9:00 AM AZST, it is 8:00 AM in Dubai, 9:00 AM in Karachi, and 4:00 AM in London during GMT or 5:00 AM in London during BST.
Against North America, AZST creates much larger gaps that matter for customer support, engineering handoffs, and international sales calls. A time of 6:00 PM AZST corresponds to 8:00 AM in New York during EST or 9:00 AM during EDT, which can make late afternoon in Azerbaijan one of the few overlapping windows with the U.S. East Coast. For the U.S. West Coast, the overlap is even tighter, since 6:00 PM AZST is 5:00 AM in Los Angeles during PST or 6:00 AM during PDT.
This offset is especially relevant for industries tied to energy, shipping, aviation, and regional trade. Baku’s role in oil and gas, Caspian transport corridors, and air links through hubs such as Istanbul, Dubai, Doha, and Moscow means planners often need to compare Azerbaijan time with Europe, the Gulf, and Central Asia rather than with a single counterpart zone.
Why AZST Still Appears in Time Conversion Searches
Many people search for AZST because they encounter it in legacy calendar exports, server logs, historical records, or enterprise software that still stores timezone abbreviations rather than modern IANA timezone identifiers. In those contexts, AZST usually means Azerbaijan Summer Time, UTC+5, and the key task is determining whether the timestamp refers to a historical date when DST was actually observed or whether the source system is using an outdated label.
This distinction matters in compliance records, flight planning archives, and multinational project documentation. A timestamp marked 10:00 AM AZST from a historical summer period would convert differently than a modern Azerbaijan meeting, because current civil time in Azerbaijan stays at UTC+4 all year. If you are reviewing older contracts, telecom logs, or operational reports tied to Baku, checking the date first is essential before assuming the offset.
Frequently Asked Questions
What does AZST stand for?
AZST stands for Azerbaijan Summer Time. It is the daylight saving time abbreviation historically used when Azerbaijan advanced its clocks to UTC+5:00, one hour ahead of its standard time, AZT (UTC+4:00).
Is AZST the same as GMT?
No, AZST is not the same as GMT. GMT is UTC+0, while AZST is UTC+5, so AZST is 5 hours ahead of GMT; for example, when it is 12:00 PM GMT, it is 5:00 PM AZST.
Which cities use AZST?
The principal city associated with AZST is Baku, the capital of Azerbaijan and the country’s main commercial and administrative center. Historically, the abbreviation applied across Azerbaijan during the summer DST period, so it was not limited to one city, but Baku is the location most users mean when searching for AZST.
What is the UTC offset for AZST?
The UTC offset for AZST is UTC+5:00. That means clocks in AZST run 5 hours ahead of UTC, so a UTC time of 06:00 corresponds to 11:00 AM AZST.
When does AZST change?
Under Azerbaijan’s historical daylight saving system, AZST would begin in late March and end in late October, switching back to AZT (UTC+4) after summer. For 2026, the historical pattern would place those changes on March 29, 2026 and October 25, 2026, but in real current practice Azerbaijan no longer observes DST, so AZST is mainly a historical reference.
Is AZST currently used in Azerbaijan?
In current civil timekeeping, no—Azerbaijan has used AZT (UTC+4) year-round since 2016. You may still see AZST in older records, software databases, or archived schedules, but modern local time in Azerbaijan does not switch to a summer offset.
Is AZST the same as PKT or UZT because they are all UTC+5?
They can match by clock time when all are at UTC+5, but they are not the same timezone label or regional standard. PKT refers to Pakistan, UZT to Uzbekistan, and AZST to Azerbaijan’s historical summer time, so the abbreviations point to different places and may have different daylight saving histories.
How far ahead is AZST from Azerbaijan standard time?
AZST is 1 hour ahead of AZT. If a schedule says 3:00 PM AZT, the equivalent summer-time clock reading would be 4:00 PM AZST, which is why historical records from different seasons in Azerbaijan need careful conversion.
