What Time Zone Am I In?

Your device already knows: this page reads your system timezone instantly, then (with permission, or a map click) confirms the official IANA timezone for any exact coordinates — with the current UTC offset and whether daylight saving time is in force right now.

Device timezone vs geographic timezone

Two different questions hide in one. Your device timezone is a setting — it follows you only if your phone updates automatically (laptops often don't, which is why meetings go wrong after flights). The geographic timezone is a fact about coordinates: which IANA zone (like Asia/Kolkata or America/New_York) governs that point on the map. This page shows both and flags when they disagree — the classic just-landed-and-my-laptop-is-wrong situation, and also one of the signals our VPN checker uses.

UTC offsets, DST, and why timezone names beat offsets

An offset like UTC+05:30 is only valid right now: half the world shifts offsets twice a year with daylight saving. IANA names encode the full rules — past and future — which is why calendars and databases store Europe/Berlin, never +01:00. Every place page on this site lists its IANA zone, and the API resolves the timezone of any coordinates programmatically.

Frequently asked questions

What timezone am I in right now?

Instantly: whatever your device is set to, shown at the top. For the official zone of your physical position, allow location (or click the map) and we resolve the IANA timezone for those exact coordinates.

Why do my laptop and phone disagree?

Phones usually update timezone automatically from the network; laptops often keep the zone you configured at setup. After travel, that mismatch is the #1 cause of calendar chaos — this page makes it visible.

What is an IANA timezone?

The standard names like Asia/Kolkata or Europe/Berlin that encode a region's full offset rules, including daylight saving history. Software stores these, not raw offsets, because offsets change through the year.
