Frequently Asked Questions
How do you calculate time across different timezones?
Our converter uses the official IANA Time Zone Database (the global standard used by Windows, macOS, and iOS). You select your base timezone and enter a time, then add as many target timezones as you need. The tool instantly calculates the exact time difference, displaying the local time for each selected city while automatically accounting for global offset rules.
What is the difference between GMT and UTC?
GMT (Greenwich Mean Time) and UTC (Coordinated Universal Time) refer to the same time zone (zero offset), but they differ technically. GMT is a time zone based on solar observations, while UTC is a precise time standard maintained by atomic clocks. In practice, they are interchangeable for most purposes. UTC is the modern standard used in computing and aviation.
How do I handle Daylight Saving Time (DST) conversions?
Our converter automatically accounts for DST. When you select a timezone, the tool applies the correct offset based on whether DST is currently active in that region. Note that DST dates vary by country — the US changes in March/November, while the EU changes in March/October. Some regions like Arizona and most of Asia don't observe DST at all.
