Timezone Quick Reference
Understanding Timezones
What are Timezones?
Timezones are regions of the Earth that observe a uniform standard time. The world is divided into 24 primary time zones, each roughly 15 degrees of longitude wide, though political boundaries often cause variations.
Daylight Saving Time (DST)
Many regions observe DST, moving clocks forward in spring and back in fall. Our converter automatically accounts for DST based on the selected date, so you always get accurate conversions.
UTC (Coordinated Universal Time)
UTC is the primary time standard by which the world regulates clocks and time. It is effectively a successor to GMT (Greenwich Mean Time) and serves as the reference point for all timezone offsets.
