Timezone abbreviation
AZOST currently resolves here through Atlantic/Azores, where the live offset is -01:00 (GMT-1). This page expands that into the broader meaning set, top cities, countries, similar labels, and safer exact-zone equivalents.
Representative zones, offset ranges, and city usage are refreshed from the current timezone dataset so abbreviation pages stay tied to real zones instead of static boilerplate.
AZOST is a European civil-time label, currently 1h behind UTC at -01:00. It maps to 1 IANA zone across 1 country, and the cities below show how the label actually spreads across the continent.
The busiest cities using AZOST in the current catalog are Ponta Delgada. The lead live reference on this page is Ponta Delgada (Atlantic/Azores), currently at -01:00 (GMT-1). Those cities are what give AZOST its actual feel rather than the abstract offset.
AZOST currently shows -01:00, but Atlantic/Azores observes seasonal clock changes — the next transition is around March 28, 2027. That means the offset on this page is a snapshot, not a permanent fact, so long-range scheduling should pin the underlying IANA zone instead of the abbreviation.

AZOST is slightly behind UTC, which keeps it within a normal trans-Atlantic working pair. In practice it is read inside Atlantic, Pacific, or Indian Ocean island cluster, where the leading city anchors are Ponta Delgada, Portugal.
AZOST is unusually unambiguous: it ties to a single country and a single IANA zone, which is closer to a national clock label than a multi-region abbreviation.
AZOST shows up on airline schedules, weather bulletins, and Pacific shipping notices more than on office calendars. AZOST can also flip to a sibling daylight-saving abbreviation later in the year, so timestamps before and after the change need to be read carefully.

Data fingerprint
This compact fingerprint is intentionally specific: exact zone IDs, place anchors, country anchors, transition cues, and offset peers. It gives humans and crawlers concrete reasons not to collapse AZOSTinto another abbreviation with the same clock hour.

Abbreviation dossier
These checks separate the abbreviation from lookalike labels and same-offset codes: the representative IANA zone, the current civil-time reading, the city/country footprint, and whether the lead zone has an upcoming clock change.
Primary live reading
Azores Time resolves through Atlantic/Azores right now: -01:00 (GMT-1).
Ambiguity status
AZOST maps to one meaning in this catalog, but the IANA zone still matters because clock-change rules live on the zone, not the short code.
DST and transition posture
Atlantic/Azores changes on March 28, 2027 at about 1:00 AM, moving from GMT-1 (-01:00) to GMT+0 (+00:00).
Country and city reach
AZOST is represented across 1 country, 1 IANA zone, and lead cities including Ponta Delgada, Portugal.
Same-offset caution
AZOST and AZOT currently share -01:00, but they point at different civil-time labels, cities, countries, and source contexts. Treat the matching offset as arithmetic only, not semantic equivalence.
Precision layer
Timezone abbreviations are useful display labels, but they are weak storage keys. This register shows the exact risks for AZOST: ambiguity, seasonal changes, same-offset neighbors, and the safer value to store in software, calendars, or operations notes.
Abbreviation ambiguity risk
LowAZOST has one meaning in this catalog, but the zone and country context still carry the legal-time rule.
Seasonal clock-change risk
MediumAtlantic/Azores changes offset in this snapshot. Next known transition: March 28, 2027: GMT-1 -01:00 to GMT+0 +00:00.
Same-offset confusion risk
Low2 other abbreviation pages currently share -01:00; the same clock hour is not the same civil-time context.
Storage recommendation
Use exact zoneStore Atlantic/Azores or a UTC instant. Display AZOST only as a human-facing label after the exact zone is known.
Coverage breadth

Four fixed UTC checkpoints expose whether AZOST crosses a local date boundary in Atlantic/Azores. This is the practical difference between a harmless clock conversion and a deadline, release, travel, or reporting mistake.
AZOST moves this checkpoint to the previous local date in Atlantic/Azores, which matters for reports, releases, travel, and deadline wording.
AZOST keeps this checkpoint on the same calendar date as UTC in Atlantic/Azores.

These abbreviation pages currently share -01:00with AZOST. They can show the same wall-clock hour while pointing at different countries, holidays, market calendars, languages, airports, and legal-time rules.
Azores Time
AZOT shares the current UTC offset with AZOST, but it is anchored to Atlantic/Azores and Portugal. Treat the shared offset as arithmetic only, not as the same holidays, cities, market calendars, or policy context.
Cape Verde Time
CVT shares the current UTC offset with AZOST, but it is anchored to Atlantic/Cape_Verde and Cabo Verde. Treat the shared offset as arithmetic only, not as the same holidays, cities, market calendars, or policy context.

AZOST is not heavily split in the current catalog, but the short label still hides the underlying IANA zone and any future policy change. The safe pattern is to write the abbreviation for humans and the zone for machines.
Atlantic/Azores has an upcoming offset change on March 28, 2027. After that point, AZOST on this page will read a different UTC offset until the next transition, so any saved timestamp should anchor to the IANA zone rather than the abbreviation.
For precise work, the safest equivalent of AZOST is the exact IANA zone used by your city or system. Atlantic/Azores sits at -01:00, behind UTC, which means daily logs in this zone reach a new calendar date after UTC does — relevant for date-aligned reports and billing cutoffs.
Within this single zone (Atlantic/Azores, -01:00), AZOST is unambiguous, so the abbreviation and the IANA zone effectively interchange.
