What is my timezone?
Your device already knows where it is in time. This page reads your IANA time zone, current UTC offset and daylight-saving status straight from your browser, and shows a live clock that ticks every second. No account, no tracking — it all runs locally.

What is a time zone?
A time zone is a region that keeps a common standard time, expressed as an offset from Coordinated Universal Time (UTC) — for example UTC-05:00. Software identifies zones by IANA names like America/New_York or Europe/London, which also encode each region's daylight-saving rules and historical changes.
How to find your time zone
- Open this page — your browser reports its time zone instantly, no permission needed.
- Read your IANA zone name, current UTC offset and whether daylight saving is in effect.
- Watch the live clock confirm your local time, and copy the zone name or offset for forms, code or support tickets.
- Optionally tap “Cross-check from my IP” to compare your device setting with your network's edge location.
Time zone notations explained
| Notation | Example | Used for |
|---|---|---|
| IANA zone ID | America/New_York | Software, calendars, scheduling APIs |
| UTC offset | UTC-05:00 | Quick math, logs, flight & meeting times |
| GMT label | GMT-5 | Everyday speech, broadcasts |
| Abbreviation | EST / EDT | Casual writing (ambiguous — avoid in code) |
| UTC time | 2026-06-13T14:00:00Z | Servers, timestamps, coordinating across zones |
Time zone vs UTC offset vs DST
A UTC offset is just a number; a time zone is the full set of rules behind it, including when daylight saving starts and ends. That's why your offset can change twice a year while your IANA zone stays the same. Always store the IANA zone, not the offset — it survives DST transitions and law changes. To pin a specific spot on a map, pair it with your coordinates or check sunrise and sunset times for that location.
Is this accurate and private?
Your time zone and offset come directly from your operating system via the browser, so they match your device exactly — no server is involved. DST status is computed by comparing your January and July offsets. The optional IP cross-check is the only step that touches the network, and even then nothing about your location is stored.

Frequently asked questions
What is my time zone right now?
Europe/Paris plus your current UTC offset and a live clock. It comes straight from your device's clock settings, so it always matches what your phone or computer shows.What is the difference between a time zone and a UTC offset?
Europe/Berlin bundles the rules behind it, including daylight saving, so its offset can change twice a year. Store the zone name, not the offset, in apps and databases.How do I know if daylight saving time is active?
Why does the IP-based time zone differ from my device?
Is this time zone checker free and private?
What is an IANA time zone name?
America/Los_Angeles are the standard identifiers software uses for time zones. Each encodes a region's offset history and daylight-saving rules, making them far more reliable than abbreviations like “PST,” which are ambiguous across countries.
