Common questions about timezone calculations and time conversion
Our timezone calculator automatically detects and adjusts for daylight saving time (DST) transitions. It uses your browser's built-in timezone database, which is regularly updated to reflect the latest DST rules for all regions. This ensures accurate time conversions year-round, even during DST transition periods.
The meeting planner rates times based on typical business hours (9 AM - 5 PM is "excellent"). Times outside normal working hours receive lower ratings. A "poor" rating means the meeting would occur very early in the morning, late at night, or during typical sleeping hours for that timezone. This helps you find meeting times that work well for all participants.
Yes, you can convert times for any date, including historical dates. However, keep in mind that daylight saving time rules have changed over the years, and some countries have modified their timezone policies. For the most accurate historical conversions, especially for dates before 2000, we recommend cross-referencing with historical timezone databases.
UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are often used interchangeably, but there are subtle differences. GMT is a timezone, while UTC is a time standard. UTC is more precise and is the basis for all other timezones. In practice, for most civilian purposes, UTC and GMT are the same. Our calculator uses UTC as the reference point for all timezone conversions.
Our timezone calculator is highly accurate and uses the same timezone database that powers most operating systems and web browsers. This database is maintained by the Internet Assigned Numbers Authority (IANA) and is updated regularly to reflect changes in timezone rules worldwide. The calculations are accurate to the minute for all supported timezones.
