Frequently Asked Questions
What is a time zone?
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones are defined as offsets from Coordinated Universal Time (UTC).
What does UTC stand for?
UTC stands for Coordinated Universal Time. It is the primary time standard by which the world regulates clocks and time. It is effectively the successor to Greenwich Mean Time (GMT).
What is Daylight Saving Time?
Daylight Saving Time (DST) is the practice of advancing clocks by one hour during warmer months so that evening daylight lasts longer. Not all countries observe DST.
How do I convert EST to CET?
Eastern Standard Time (EST) is UTC-5 and Central European Time (CET) is UTC+1. To convert from EST to CET, add 6 hours. During daylight saving, the offset may change.
Convert times across zones
A time zone converter shows what a given time is in other parts of the world, taking daylight saving into account. Pick a time and the zones you care about, and see them side by side.
