How Our Time Zone Converter Works

Select two time zones from the dropdowns (covering the USA, Canada, UK, Europe, Australia, Japan, India, the Middle East, Africa, South America, and more). Enter a date and time, and the tool instantly shows the converted time in the target zone. It accounts for Daylight Saving Time (DST) automatically.

The live world clock displays the current time in major cities, and the popular conversions panel gives one‑tap access to commonly searched pairs like EST to GMT or PST to IST. All conversions happen locally in your browser — no data is ever sent anywhere.
