How to Use the Time Zone Converter
Our time zone converter lets you instantly and accurately convert times between any city in the world. It supports over 400 cities and all 38 existing time zones, including those with half-hour offsets like India (UTC+5:30) and Central Australia (UTC+9:30).
Time conversion: Select your source and destination cities, enter the time, and get instant conversion. The system automatically accounts for daylight saving time (DST), so results are always accurate regardless of the time of year.
World clock: Add cities you care about and monitor local time in real-time. Perfect for those working with international teams, clients abroad, or following events in different time zones. The clock updates automatically every second.
Meeting planner: Add all participants' time zones and automatically find the best meeting time. The system highlights business hours (9 AM-6 PM) in green, acceptable hours in yellow, and off-hours in red. Ideal for globally distributed teams.
This tool is completely free, runs entirely in your browser, and requires no sign-up. Calculations use the browser's native Intl.DateTimeFormat API, which guarantees absolute accuracy, including automatic daylight saving time handling for every single zone.
