    FAQ

    Is anything sent to a server?

    No. The clock and every conversion are worked out in your browser using its built-in time-zone data, so nothing you type is uploaded. The tool keeps your dates private.

    Does it handle daylight saving time?

    Yes. It uses your browser’s official IANA time-zone database, which knows each region’s daylight-saving rules, so the offsets and converted times follow the correct summer or winter time for the date you pick.

    Which time zone is mine?

    Your own zone is detected automatically and shown at the top. The world clock then lists how many hours each city is ahead of or behind you, so you can compare at a glance.
