How to use this tool
Overview
Timezone Converter - World Clock & Meeting Planner converts any date and time between timezones accurately. Pick a date, choose the source and target zones, and get the converted time with its UTC offset and the exact difference in hours and minutes — daylight saving is applied automatically for the selected date using the IANA database built into your browser. A live world clock shows the current time in UTC, New York, London, Berlin, Dubai and Tokyo, updated every second with a day indicator when the date differs. Useful for remote teams, travel planning, flight times, support coverage and scheduling calls across regions. Everything runs locally; nothing is uploaded.Frequently asked questions
Is daylight saving time handled? +
Yes. The Timezone Converter - World Clock & Meeting Planner uses your browser Intl API, which includes the full IANA timezone database — so EST/EDT, GMT/BST and every other seasonal change is applied automatically for the selected date.
Why do the offsets look different on some dates? +
Timezone offsets are computed for the specific date you entered, not today. A date in January and a date in July can show different offsets for the same zone.
What is UTC? +
UTC (Coordinated Universal Time) is the world time standard with no offset. Converting a local time to UTC is the safest way to share a meeting time across regions.
Is anything sent to a server? +
No. Timezone data comes from your browser built-ins and all calculations run locally. Nothing is uploaded.
