Convert current time or any custom time between any two cities worldwide. Supports 150,000+ cities with live clocks, AM/PM format, and automatic DST handling.
Free • Live • 150K+ CitiesOur time zone converter is the simplest way to find the exact time difference between any two cities on Earth. Whether you are scheduling an international business call, planning a flight, or checking what time it is for a friend overseas, this tool gives you instant, accurate results.
Unlike basic time zone charts, our converter accounts for Daylight Saving Time (DST) automatically. This means you never have to manually adjust for seasonal clock changes — the tool knows whether DST is currently active in each city and factors it into the calculation.
The converter supports two modes:
With coverage of 150,000+ cities across 250+ countries and territories, you can convert between virtually any two locations — from major capitals like London, Tokyo, and New York to smaller regional cities.
The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. However, political and geographic boundaries mean actual time zone borders are irregular. Some countries span multiple time zones (the USA has 6, Russia has 11), while others use half-hour or quarter-hour offsets (India is UTC+5:30, Nepal is UTC+5:45).
Coordinated Universal Time (UTC) is the global reference point. Every local time is expressed as an offset from UTC. For example:
The maximum time difference between two places is 26 hours (UTC−12 to UTC+14), though most commonly used offsets range from UTC−11 to UTC+12.
When you use our converter, you are not just doing simple math. The tool queries live timezone databases that know the exact DST rules for every region — including the dates when clocks spring forward or fall back.
Select the country and city you are converting FROM, then the country and city you are converting TO. Choose "Current Time" to see the live time now, or "Custom Time" to enter a specific time. Click Convert and the result will show the exact local time, date, and time difference.
Yes. The converter automatically detects whether DST is currently active in both cities and adjusts the calculation accordingly. You never need to manually add or subtract an hour for seasonal time changes.
The maximum possible time difference is 26 hours — between Baker Island (UTC−12) and the Line Islands (UTC+14). For major cities, the largest common difference is about 19–20 hours (e.g., Los Angeles to Auckland).
Yes. Click the "Custom Time" button above the form, enter the time you want (in 24-hour format), and select your cities. The converter will show what that exact time equals in the destination city.
Countries near the equator (like India, Singapore, and most of Africa) have relatively consistent daylight hours year-round, so shifting clocks provides little benefit. Countries closer to the poles benefit more from DST because daylight varies dramatically between summer and winter.
The converter supports over 150,000 cities across 250+ countries and territories. This includes every major capital, business hub, and travel destination, plus thousands of smaller regional cities.
