Map of Time Zones – World Clock, UTC & Global Time Guide

This map of time zones provides a detailed overview of global time regions, including UTC offsets, international time boundaries, daylight saving regions and major world cities.

World time zones help coordinate international travel, business, communication, aviation, shipping and global events across different countries and regions.

How World Time Zones Work

World time zones are generally based around UTC (Coordinated Universal Time), with countries and regions using positive or negative hour offsets from UTC.

• UTC+ regions — located east of the Prime Meridian
• UTC- regions — located west of the Prime Meridian
• Prime Meridian — passes through Greenwich, London
• International Date Line — separates calendar days in the Pacific Ocean

Major Global Time Zone Regions

• North America time zones — include Eastern, Central, Mountain and Pacific time
• Europe time zones — include GMT, CET and EET regions
• Australia time zones — include AWST, ACST and AEST regions
• Asia time zones — span from the Middle East to Japan and China
• Pacific island time zones — include some of the world’s earliest calendar dates
• South America time zones — vary across tropical and southern regions
• Africa time zones — centred around GMT and UTC+ regions

Important Time Zone Features

• UTC reference system — global standard for coordinated time
• Daylight saving time — seasonal clock changes in some countries
• International Date Line — major calendar boundary in the Pacific
• Half-hour and quarter-hour zones — used in some countries and territories
• Cross-border time differences — affect travel and communication

Common Uses for Time Zone Maps

• International business meetings — coordinate work across countries
• Travel and aviation planning — manage flight and arrival times
• Global live events — convert broadcast and event schedules
• Shipping and logistics — coordinate international operations
• Online communication — manage remote teams and calls
