Understanding Time Zones and Global Time Management

Learn about time zones, daylight saving time, and how to effectively manage time across different regions

What are Time Zones?

Time zones are regions of the Earth that observe a uniform standard time for legal, commercial, and social purposes. They are based on the Earth's rotation and divided into 24 main zones, each approximately 15 degrees of longitude apart.

Key Concepts:

  • UTC (Coordinated Universal Time): The primary time standard
  • GMT (Greenwich Mean Time): Based on the Prime Meridian
  • DST (Daylight Saving Time): Seasonal time adjustments
  • IANA Time Zones: Standardized timezone identifiers

Daylight Saving Time (DST)

DST is the practice of advancing clocks during warmer months to extend evening daylight. Not all countries observe DST, and those that do have different start and end dates.

DST Rules:

  • United States: Second Sunday in March to first Sunday in November
  • European Union: Last Sunday in March to last Sunday in October
  • Australia: First Sunday in October to first Sunday in April
  • No DST: Most of Asia, Africa, and parts of South America

World Time Zone Converter FAQ

Frequently asked questions about timezone conversion

How accurate is the DST handling?

Our converter uses the latest DST rules for each timezone. However, DST rules can change, so for critical applications, always verify with official sources. The converter automatically detects DST transitions and adjusts times accordingly.

Can I add custom cities?

Currently, the converter includes major cities worldwide. You can save frequently used conversions as favorites for quick access. Custom city support may be added in future updates.

How does the team overlap heatmap work?

The heatmap shows working hours overlap (9 AM - 5 PM local time) between selected cities. Green indicates good overlap, yellow moderate overlap, and red minimal overlap. This helps identify optimal meeting times.

Can I share meeting links with specific times?

Yes! Use the "Share Meeting Link" button to generate a URL with prefilled times for both cities. This makes it easy to share meeting times with team members in different time zones.
