World Clock — Multiple Cities

Adding and removing cities: Type any city name in the search box and select from the results. Cities are displayed in a column showing local time, UTC offset, and day-of-week. Remove a city by clicking the X on its card. Your city list persists in browser local storage between visits.

Reading the day/night globe: The globe shows the current position of the solar terminator. Cities in the lit hemisphere are in daylight; cities in the dark hemisphere are in nighttime. The globe rotates in real time — you can watch the day-night boundary sweep across the Earth.

Common use cases by team configuration:

• ·US East + West coast: New York (ET) and Los Angeles (PT) — 3-hour difference
• ·US + UK team: New York (ET) and London (GMT/BST) — 5–6 hours
• ·US + India: New York (ET) and Mumbai (IST) — 9.5–10.5 hours
• ·Europe + Asia-Pacific: London (GMT/BST) and Singapore (SGT) — 7–8 hours

vs a time zone converter: A converter lets you input a specific time and see it in multiple zones. A world clock shows the current time in all zones simultaneously — no input required. Use a world clock for ambient awareness; use a converter for specific scheduling.

vs checking your phone's clock app: Phone clock apps support adding world clocks in the list view. The advantage of a browser world clock is that it is visible on a second screen or in a browser tab while you work, without requiring you to pick up your phone.

vs time zone widgets in a calendar app: Calendar world time widgets show current times but are confined to the calendar interface. A browser clock is accessible from any tab and is not tied to a specific app.

A world clock shows the current local time in multiple cities simultaneously — so you can glance at one screen and know whether your colleague in Tokyo is starting their workday, whether it is the middle of the night in Berlin, or whether you have reached business hours in São Paulo.

For distributed teams, freelancers with international clients, travelers, or anyone with family in different countries, a world clock removes the mental arithmetic of time zone conversion from routine daily awareness. You add the cities you care about and the clock shows you their current time at a glance — no conversion, no calculation, just the time.

This world clock shows the current time in each city, updated live. A day/night globe visualizes the solar terminator — the line between day and night across the Earth — so you can see at a glance which regions are in daytime and which are in darkness. The globe rotates in real time as the Earth turns.

DST is handled automatically. When a city transitions in or out of Daylight Saving Time, the displayed offset updates without any manual intervention. You always see the correct current local time regardless of seasonal shifts.
