World Clock — Track Time Zones Globally

TimeMaster's World Clock displays the current local time for cities around the globe. Whether you are coordinating with international colleagues, planning travel, or simply curious about the time in another part of the world, our tool provides accurate, real-time information with automatic daylight saving time adjustments.

How Time Zones Work

The Earth is divided into 24 primary time zones, each offset from Coordinated Universal Time (UTC). As you move east from the Prime Meridian (0° longitude in Greenwich, England), each zone is one hour ahead. Moving west, each zone is one hour behind. However, many countries have adopted time zones that do not follow strict 15-degree meridian lines, creating offsets like UTC+5:30 (India) or UTC+9:30 (parts of Australia).

Understanding Daylight Saving Time

Many countries observe Daylight Saving Time (DST), shifting clocks forward by one hour in spring and back in autumn. This means the time difference between two cities can change throughout the year. For example, the difference between New York and London is 5 hours during winter but only 4 hours during summer, because the US and UK switch their clocks on different dates. Our World Clock automatically handles these changes, always showing the correct current time.
