About this tool
A free live clock & world clock, accurate to the second
Welcome to your free live clock and world clock — a fast, accurate online clock with seconds that answers one simple question: what time is it now? Whether you need the current time in your own city or across several time zones at once, this digital clock online updates in real time, with no signup and no clutter. It works the same on mobile and desktop, so the current time is always one tap away.
A live clock with real-time seconds
This is a true live clock: the seconds tick in real time, not on a lazy once-a-minute refresh. The display is synced to a network time source, so the current time you see stays accurate even when your device's own clock has drifted. Prefer a big, glanceable readout? Switch to full screen clock mode and turn any monitor, tablet, or phone into a dedicated digital clock.
World clock for multiple time zones
The world clock online lets you compare the current time in different time zones side by side. Add the cities you care about and watch a true time zone clock for each one, including a UTC clock and GMT time reference. It's world time without the math — no counting hours forward or backward, no guessing whether a city has crossed into a new day. Need to convert one exact moment? Use the time zone converter.
12/24-hour and full-screen modes
Read time the way you prefer. Toggle the 24 hour clock or classic 12-hour AM/PM format with a single click, and your choice is remembered. Full-screen mode strips everything away for a clean, distraction-free digital clock online — ideal for a desk display, a studio monitor, or a shared screen in a meeting room.
Who it's for
Remote teams use this world clock to schedule calls across continents without a single timezone mix-up. Streamers and broadcasters keep a full screen clock on a second monitor to stay on cue. Students, travelers, and anyone juggling deadlines use the live clock to confirm the current time in different time zones at a glance. Planning a call? The meeting planner highlights when everyone's working hours overlap.

Answers
Frequently asked questions
What time is it right now with seconds?
The exact current time with live seconds is displayed at the top of this page, ticking in real time. The clock refreshes every second and syncs to a network time source, so you always see the precise current time rather than a stale, once-a-minute reading.
How accurate is this online clock?
This clock is accurate to within a fraction of a second. It syncs to a network time source instead of trusting your device, then corrects for network delay. It also detects when your own device clock has drifted, so the displayed time stays reliable.
How does the clock get the exact time?
The clock fetches the time from a network time source over the internet, similar to NTP. It measures the round-trip delay, compensates for it, and then counts seconds locally in your browser. This keeps the displayed time precise without constant network requests.
Why is the time slightly different from my phone or computer?
Because your device's clock has likely drifted. Phones and computers gradually gain or lose a few seconds between syncs, while this clock corrects against a network time source in real time. The small gap you see is usually your device being slightly off, not this clock.
Can I switch between 12-hour and 24-hour (military time) format?
Yes. You can switch between 12-hour AM/PM and 24-hour (military time) format with a single click, and your choice is remembered for next time. The 24-hour clock is ideal for international teams, transport schedules, and avoiding any AM/PM confusion.
Can I view the clock in full screen?
Yes. Full-screen mode turns any device into a clean, distraction-free clock display. Just enable full screen and the time fills your monitor, tablet, or phone — perfect for a desk clock, studio monitor, or shared meeting-room screen, with no menus or clutter in view.
Does the clock keep ticking if I leave the tab open or minimized?
Yes. The clock keeps running while the tab is open, minimized, or in the background. When you return, it re-syncs to the network time source so the time is accurate immediately, even if your device was asleep for a while.
Can I use this clock as an OBS / live-stream overlay or a room display?
Yes. Many streamers add it as an OBS browser source or window overlay, and teams run it full screen as a wall or room display. Use full-screen mode for a clean look, and it keeps ticking in real time while you broadcast.
Does the clock work offline?
Partly. Once the page has loaded, the clock keeps counting seconds locally even if your connection drops, so it still ticks. However, it can only re-sync and correct for drift when you're back online, so accuracy is best with an active connection.
What is the current time in different time zones right now?
You can see the current time in multiple time zones right now using the world clock. Add any cities and each one shows its live local time side by side, including UTC and GMT, so you can compare them at a glance without any manual math.
How do I check the time in another city (e.g., New York, London, Tokyo)?
Search for the city — such as New York, London, or Tokyo — and add it to your world clock. Its current local time then updates live alongside your other cities, automatically adjusted for that location's time zone and Daylight Saving rules.
What is the time difference between India and the USA (or any two cities)?
It varies, because the USA spans several time zones. India (IST) is roughly 9.5 to 12.5 hours ahead of the US mainland, depending on the US zone and Daylight Saving. Add both cities to the world clock to see the exact, current difference.
What is UTC and how is it different from GMT and my local time?
UTC (Coordinated Universal Time) is the global time standard from which all time zones are offset. It is practically identical to GMT, though UTC is the modern, more precise reference. Your local time is simply UTC plus or minus your time zone's offset.
Does the clock automatically adjust for Daylight Saving Time (DST)?
Yes. Each city's time automatically follows its local Daylight Saving Time rules, switching forward or back on the correct dates. You never have to add or remove an hour yourself — the world clock always shows the correct current local time.
How many time zones are there in the world?
There are 24 main time zones based on one-hour offsets from UTC, but in practice around 38 to 40 are in use. Some regions use 30- or 45-minute offsets, such as India (UTC+5:30) and Nepal (UTC+5:45), which adds the extra zones.
How do I compare times across multiple cities to schedule a meeting?
Add every city to the world clock and view their current times side by side. For finding a meeting slot, the meeting planner shows overlapping working hours across all locations, so you can pick a time that works for everyone at a glance.
Why is my time zone showing the wrong time?
Usually your device is set to the wrong time zone or has an incorrect date. Check your system's date, time, and time-zone settings, and make sure automatic time zone is enabled. You can also select your correct city manually so the clock shows your true local time.
