Frequently asked questions
How does the Time Zone Converter work?
You enter a date and time in the starting zone, and the tool shows the exact same moment in the target zone using your browser's built-in time zone data — including daylight saving rules.
Does it handle daylight saving time?
Yes. The conversion uses the official rules for each zone on that exact date, so summer and winter offsets are applied correctly.
Which cities are included?
More than 30 common business and travel zones, including Karachi, Delhi, Dubai, London, New York, Tokyo and Sydney — plus UTC.
Is it free?
Yes, completely free with no sign-up, and nothing you enter leaves your device.
