Understanding Time Zones
Learn about time zones, UTC, and daylight saving time
UTC/GMT Explained
Coordinated Universal Time (UTC) is the primary time standard. GMT (Greenwich Mean Time) is often used interchangeably with UTC for civilian purposes.
Daylight Saving Time
Many regions observe daylight saving time, shifting clocks forward in spring and back in autumn. This affects time zone offsets seasonally.
Business Hours Matter
When scheduling international meetings, consider typical business hours (9 AM - 5 PM) in each participant's time zone.
Global Meeting Tips
Use 24-hour format to avoid AM/PM confusion. Include time zones in all communications. Consider rotating meeting times for fairness.

Time Zone Converter FAQ
Common questions about UTC, daylight saving time, offsets, and meeting planning.
What is the difference between UTC and a time zone?
UTC is the global reference time. A time zone is a named region, such as America/New_York, that can have different UTC offsets during the year.
Why do time zone offsets change?
Some regions use daylight saving time, which shifts the local offset for part of the year. Other regions stay on the same offset year-round.
How should I plan a meeting across time zones?
Add each participant city, compare local business hours, and choose a time that avoids very early mornings or late evenings for the group.
Is GMT the same as UTC?
They are often used similarly for everyday conversion, but UTC is the precise modern time standard used for offsets and computing.
Does the converter handle daylight saving time?
The converter uses browser time-zone data for current offsets and daylight-saving behavior where that data is available.
