    Each clock reads your browser's IANA time-zone data, so daylight saving is applied automatically.

    Compare time zones side by side

    Each column is the same moment (hours of today in UTC). Rows show what the local clock reads in each city.

    Working hours here are a typical example (09:00-17:00). The Meeting Time Finder lets you set your own hours per location.

    A sample of the kind of view the World Meeting Planner produces. The green blocks are slots inside everyone's working hours; the dashed block shows a compromise slot outside someone's hours.

    How it works

    1. Pick your cities

      Choose real IANA time zones such as Asia/Riyadh or Europe/London, not guessed offsets.

    2. Set the date and time

      The date matters, because daylight saving rules change the gap between cities during the year.

    3. Share the result

      See each city's local time and day, then copy the details into your invitation.

    Built for remote teams and international scheduling

    Real time-zone data

    Offsets come from the IANA database, including daylight saving, never from a fixed table.

    Honest about problems

    Nonexistent and repeated clock times are flagged instead of silently converted.

    Private by design

    No accounts. Your entries stay in your browser and are not stored on our server.

    Frequently asked questions

    Is it really free?

    Yes. Every public tool is free, with no signup, login or subscription.

    Does it handle daylight saving time?

    Yes. Offsets are looked up from IANA time-zone data for the exact date, so the gap between two cities can change during the year.

    What happens at a clock change when a time does not exist?

    If a local time is skipped (clocks move forward), the planner tells you and asks for a valid time. If a time happens twice (clocks move back), it warns you about the ambiguity.

    Is my data stored?

    Not on our server. Theme, language and time-format choices are saved in your browser only, and you can clear them from the footer.

    Why might results differ slightly from another tool?

    Governments occasionally change time-zone rules, and browsers and servers update their databases at different times. For critical events, confirm with participants.

    Which tools are available?

    All 20: world clocks, time zone and UTC converters, meeting planners and finders, date and duration calculators, a countdown timer, week-number, working-day and business-day calculators, and a Unix timestamp converter.
