What is my timezone and current local time?

Yes, World Clock is completely free to use, with no catch. You don't need an account, there is nothing to sign up for, and there is no trial that expires or paywall waiting further down the page. You can open it as often as you like, leave it running all day, and check your local time, time zone, UTC offset, and IANA ID as many times as you want — there is no usage limit. It runs in any modern browser on desktop, tablet, or phone, with no app to install and no extension required. Nothing you see is uploaded: the clock works entirely on your device, so the values it shows are never sent anywhere. It is one of the free LK Forge tools, built simply to be useful whenever you need it.

This page detects your time zone automatically from your browser and shows it in the Timezone panel below the clock — there is nothing to type in or look up. You'll see the long name (such as Pacific Standard Time), the short abbreviation, and the matching IANA ID like America/Los_Angeles. Detection is browser-based: the value comes straight from your device's own date-and-time settings, so it reflects wherever you are right now and updates if you travel or your system clock changes. The displayed name also follows daylight saving time, switching between standard and summer time at the right moment for your region. It is handy for confirming your zone before a remote meeting, filling in a calendar invite, or setting a server. If it ever looks wrong, check your computer or phone's date-and-time settings, because that is the single source this page reads.

Your UTC offset is the difference between your local time and Coordinated Universal Time, shown here in the Offset cell as something like UTC+01:00. A positive offset means you are ahead of UTC (generally east), and a negative offset means you are behind it (generally west). For example, an offset of UTC+05:30 corresponds to India Standard Time, so when it is 12:00 in London it is 17:30 in Mumbai. The offset can change during the year if your region observes daylight saving time, and this page always shows the offset that is currently in effect rather than a fixed yearly value. It updates live, so you can trust it even right after a clock change. Knowing your offset makes it quick to work out the gap between two cities before you schedule a call or a deadline.

An IANA time-zone ID is a standardized identifier maintained in the global time-zone database, written as Area/Location — for example Europe/Paris or America/Chicago. Unlike a plain offset, it captures a region's complete history and rules for time, including when daylight saving starts and ends. Take America/New_York: a single ID that automatically covers both EST in winter and EDT in summer, so you never have to track the switch yourself. Developers rely on these IDs because they stay correct even when governments change the rules, which happens more often than most people expect. Storing the IANA ID rather than a raw offset is the safe way to record a user's zone in a database or app. This page shows your IANA ID and lets you copy it with one click for use in code or configuration.

Twelve-hour time runs from 1 to 12 and uses AM and PM to mark morning and afternoon, while 24-hour time runs from 00:00 to 23:59 with no AM or PM needed. The 24-hour format is common in much of the world and in technical contexts because it removes any ambiguity about which half of the day you mean. Both describe exactly the same moment — only the labeling differs. Use the 12h/24h toggle at the top of the clock to switch between them instantly.

No. Everything on this page runs entirely in your browser using its built-in JavaScript time APIs, and nothing about your time, time zone, or location is uploaded, logged, or stored on any server. The clock never asks for GPS or location permission — your time zone is read from your device's own settings, and that value stays in the browser. There is no account, no sign-up, and no tracking of the specific values shown to you. Because all the work happens locally, you can keep the page open and it will keep ticking even if you go offline once it has loaded. That makes it safe to use for sensitive scheduling, for checking a colleague's working hours, or simply as a reliable desk clock, without worrying that your whereabouts are being shared or recorded.

Use the converter on this page: pick the UTC offset you're working with from the dropdown — anything from UTC-12 to UTC+14 — and either keep the current time or type the specific time you care about. The tool instantly shows what that moment is in your own local time, detected automatically from your browser, along with the matching date. Because every place on Earth shares the same instant, converting comes down to the gap between the chosen offset and your own offset: if you are at UTC+02:00 and you pick UTC-04:00, you are six hours ahead, so 3:00 PM there is 9:00 PM for you. The page also shows a live sentence that updates every second, telling you what time it is right now at the offset you selected versus where you are, so you never have to do the arithmetic by hand.

"UTC-4 to my time" is a request to translate a time given in the UTC-04:00 zone into your own local time. UTC-4 means four hours behind Coordinated Universal Time — it covers places like Eastern Daylight Time in summer or Atlantic Standard Time year-round. To answer it you only need the difference between UTC-4 and your local offset. Select UTC-04:00 in the converter above and the page does this for you: it reads your device's current offset, works out the gap, and prints the equivalent local time and date, flagging when the result lands on the previous or next day. For example, if you are in London during summer (UTC+01:00) you are five hours ahead of UTC-4, so a 6:00 PM meeting there is 11:00 PM for you. The same approach works for UTC-5, UTC+2, UTC+9 or any other offset.

Yes. The offset dropdown includes every real-world fractional zone, not just whole hours. You'll find the half-hour offsets such as UTC+05:30 (India), UTC+03:30 (Iran), UTC+09:30 (parts of Australia) and UTC-03:30 (Newfoundland), as well as the unusual 45-minute offsets UTC+05:45 (Nepal), UTC+08:45 (parts of Western Australia) and UTC+12:45 (Chatham Islands). The conversion math works in minutes rather than whole hours, so these are handled exactly with no rounding. One thing to keep in mind: the dropdown lists fixed offsets, not named regions, so it does not apply daylight-saving rules for the source location — pick the offset that is actually in effect there at the moment. Your own side is always accurate, because your browser already accounts for your local daylight-saving changes automatically.
