Introducing World Clock — Many Cities, One Live Board

World Clock is now live on Tools.Town — a single board that shows the current time in up to 12 cities at once, each card ticking live, each labelled with its UTC offset, zone abbreviation and a marker when the date has rolled over. No sign-up, no servers, no mental arithmetic across uneven offsets.

What It Does

Add cities from a searchable picker of 30 popular zones — or one-tap quick chips — and watch them tick:

• Live local time for every city, updating once per second.
• UTC offset in standard ±HH:MM form, including the awkward half-hour and 45-minute zones like India’s +05:30 and Nepal’s +05:45.
• Zone abbreviation (IST, EDT, CET…) shown alongside the full identifier so there’s no ambiguity.
• Next-day / Previous-day markers comparing each city to the first on your board, so cross-midnight scheduling is obvious.

When you’re done, “Copy times” drops the whole board into your clipboard as clean text, ready to paste into a chat or a calendar invite.

How It Works

Everything runs 100% in your browser using the built-in Intl API and the IANA tzdata that ships with every modern operating system — the same database your phone already trusts. Because the computation happens locally, the cities you add and the times shown never leave your device, and the clocks stay accurate through daylight-saving transitions with nothing for us to push.

Why We Built It

“What time is it there?” is a five-second question that should not require four browser tabs. For anyone working with a remote team, juggling clients abroad or calling family across borders, seeing all the relevant clocks side by side turns scheduling from guesswork into a glance. The “Next day” tags alone prevent the classic mistake of booking a call on the wrong calendar day.

If you want the bigger picture behind the cards, our How a World Clock Works guide walks through UTC offsets, daylight saving and why dates roll over between zones. When you need to pin down one precise moment instead of watching the clocks, reach for the Timezone Converter or inspect a single zone with Time Zone Info.
