Detecting timezone...
Frequently Asked Questions
How does this tool detect my timezone?
This tool uses the JavaScript Intl.DateTimeFormat API to read your timezone directly from your operating system's settings. It doesn't use your IP address or location — it reads what your device is configured to.
What is UTC offset?
UTC offset is the difference in hours (and sometimes minutes) between your local time and Coordinated Universal Time (UTC). For example, New York is UTC-5 in winter and UTC-4 during daylight saving time.
What is DST and does it affect my timezone?
DST (Daylight Saving Time) is the practice of moving clocks forward one hour in spring and back in fall. It changes your UTC offset temporarily. Not all countries observe DST — it depends on your region.
Why is my timezone showing wrong?
If your timezone appears incorrect, check your device's date and time settings. Most devices set timezone automatically based on location, but this can be overridden manually. VPNs don't change your timezone — only your device settings do.
What is the IANA timezone format?
IANA timezone names like 'America/New_York' or 'Europe/London' are the standard identifiers used in software. They account for historical timezone changes and DST rules, making them more reliable than simple UTC offsets.
