What Is My Timezone
Your timezone
Detecting…
Current local time
--:--:--
Detected from your browser's locale settings, not your IP address. All values are read locally.
How to use
- Open the page — your timezone name and UTC offset appear at the top automatically.
- Watch the live local clock to confirm the detected time matches your wall clock.
- Copy the IANA timezone name (for example America/New_York) to use in code, calendars, or support tickets.
FAQ
What timezone am I in?
The headline shows your IANA timezone name — such as America/New_York or Europe/London — detected from your browser's locale settings. Below it you see the matching UTC offset and a live clock.
What is my UTC offset?
Your UTC offset is shown as a value like UTC+07:00 or UTC-05:00. It is the difference between your local time and Coordinated Universal Time, including any daylight saving adjustment currently in effect.
What is an IANA timezone name?
IANA names (also called tz database names) look like Region/City, for example Asia/Tokyo. They are the standard identifiers used by operating systems, programming languages, and calendar apps because they encode historical and DST rules, not just a fixed offset.
Does this use my IP address?
No. The timezone is read from your browser's own locale settings via the Intl API. This reflects how your device is configured, which can differ from an IP-based location guess — useful when you travel or use a VPN.
Why does my offset differ from a friend in the same country?
Large countries span multiple timezones, and daylight saving time starts and ends on different dates by region. The IANA name plus the live offset shown here capture the exact rules for your location right now.
Is any data sent to a server?
No. Everything is detected and displayed locally in your browser. Nothing about your timezone or clock is uploaded or stored.
Introduction
What Is My Timezone tells you, at a glance, which timezone your device thinks it is in, what your offset from UTC is, and what your local time is right now. It reads this straight from your browser's locale configuration — not from a rough IP-based guess — so the answer matches how your system is actually set up.
This is handy whenever time matters across locations: scheduling a call with a remote team, setting a cron job, debugging a "wrong timestamp" bug, or simply confirming your clock after travel.
What this tool shows
| Field | Meaning |
|---|---|
| IANA timezone | The standard Region/City identifier, e.g. Asia/Tokyo. |
| UTC offset | Your current difference from UTC, e.g. UTC+09:00, including DST. |
| Abbreviation | The short zone label your locale uses, e.g. JST, EST, CET. |
| Local time | A live, ticking clock for your detected timezone. |
| Locale | The BCP 47 locale tag driving date and number formatting. |
IANA name vs UTC offset
A UTC offset like UTC+02:00 is only a snapshot — it changes when daylight saving starts or ends. An IANA timezone name like Europe/Paris is the durable identifier: it encodes the full set of rules, including when DST flips. That is why software and calendars store the IANA name rather than a bare offset, and why you should prefer copying the IANA name when configuring systems.
Common use cases
- Scheduling across regions — confirm your offset before agreeing on a meeting time.
- Configuring software — paste your IANA name into cron displays, database settings, or calendar apps.
- Debugging timestamps — verify your local offset when a UI shows the wrong date or time.
- After travel or VPN use — check whether your device timezone updated to match where you are.
Best practices
- Prefer the IANA name over a raw offset whenever you store or share a timezone, so daylight saving is handled automatically.
- Remember this reflects your device setting, which may lag reality if you just changed locations — update your OS clock if the live time looks wrong.
- To convert a specific time between zones, use the timezone converter; to work with epoch values, try the unix timestamp tool.
