About TimeZoneLive
TimeZoneLive is a free reference for current time around the world. It answers two questions: what time is it somewhere right now, and what is the gap between two places today — not in theory, but accounting for whichever daylight saving rules are in force at this moment.
Why this site exists
Most “time difference” answers you find online are static numbers. They are correct for part of the year and quietly wrong for the rest of it. The gap between London and New York is five hours for most of the year, but for roughly two weeks each spring and autumn it is four hours, because the United Kingdom and the United States change their clocks on different dates.
A page that prints “5 hours” and stops there will mislead you during exactly the weeks when you are most likely to miss a meeting. Every clock on this site reads the current instant from your browser and formats it with the target zone’s rules as they apply right now, so those transition weeks are handled without you having to think about them.
Where the data comes from
Offsets, daylight saving rules, and transition dates come from the IANA Time Zone Database, the same dataset used by Linux, macOS, iOS, Android, Java, and most server software. It is maintained collaboratively and updated several times a year as governments change their rules — which they do more often than most people expect.
This site does not ship its own copy of that database. Clocks are rendered with the browser’s built-in Intl.DateTimeFormat API against IANA zone identifiers such as Asia/Kolkata and America/New_York. Your device already carries current time zone data, and this site defers to it rather than second-guessing it.
Known limits
Being straight about what this site does not do:
- Abbreviations like CST are genuinely ambiguous. CST is US Central Standard Time at UTC−6 and China Standard Time at UTC+8. Where this site uses abbreviations it names the underlying IANA zone alongside them, but if precision matters, prefer the zone identifier.
- Live clock accuracy depends on your device’s system clock. If your computer’s time is wrong, every clock here will be wrong by the same amount.
- A handful of regions observe offsets that are not whole hours — India at UTC+5:30, Nepal at UTC+5:45, parts of Australia at UTC+9:30. Differences involving these are shown with fractional hours rather than rounded.
- Time zone rules change by government decision, sometimes with only weeks of notice. If your device has not received a recent time zone data update, a newly changed rule may not be reflected.
How the site is funded
TimeZoneLive is free and carries advertising. Ads are kept out of the clock displays and conversion results so they never obscure the answer you came for. The site does not sell user data. Details of what is collected are in the privacy policy.
Who runs it
TimeZoneLive is built and maintained by Bharadwaj Daya, an independent developer. It started as a personal tool for coordinating work across the India–US time gap and grew into a public reference. Corrections are genuinely welcome — particularly reports of a zone whose rules changed and whose page here is now stale. Reach me through the contact page.
