About WorldHourly

Last updated October 20, 2026

WorldHourly.com is a world clock, meeting planner and set of date and time calculators for people who work, travel or keep in touch across time zones.

What it does

• World clock: line up to 8 places, drag the day bands to compare hours, and copy every time at once.
• Date and time calculators: add or subtract time and measure durations across time zones, with daylight saving changes handled and explained.
• Meeting planner: see which hours are good, workable or outside working hours for everyone.
• Ask WorldHourly: type a time question in plain English, such as "3pm in London in Tokyo".
• Time zone directory: every IANA time zone your browser supports.

Where the times come from

Time zone rules, including daylight saving changes, come from the IANA time zone database built into your browser, read through the Luxon library. All calculations run on your own device. Governments sometimes change their clock rules at short notice, so double-check anything critical close to the date.
