About Time Zone Conversion
What is a Time Zone?
A time zone is a region where the same standard time is used. The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. The primary reference is Coordinated Universal Time (UTC), and other zones are expressed as offsets from UTC.
Daylight Saving Time (DST)
Many regions observe DST, advancing clocks by one hour during warmer months. Our converter automatically accounts for DST changes, ensuring accurate time conversions regardless of the season.
