Effortless Time Zone Conversion

A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. The world is divided into 24 main time zones, each roughly 15 degrees of longitude wide.

Our converter uses your selected time and time zones to calculate the correct local time in another region, accounting for daylight saving time changes and other local time variations. We use the latest timezone data to ensure accuracy.

The difference in hours between time zones is due to the Earth's rotation and the way time zones are set by countries and regions. Some regions may have fractional hour differences (like 30 or 45 minutes) from UTC due to historical or geographical reasons.

Daylight Saving Time is the practice of advancing clocks during summer months to extend evening daylight. Typically, clocks are moved forward by one hour in spring ("spring forward") and back by one hour in fall ("fall back"). Our converter automatically accounts for DST changes in all supported regions.

GMT (Greenwich Mean Time) is a time zone used in some countries, while UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. For most practical purposes, UTC and GMT are equivalent, but UTC is the modern scientific standard that replaced GMT.

If your conversion seems incorrect, check if both locations might be in a DST transition period. Also, verify you've selected the correct cities and date, as some places change their time zone rules occasionally. If you still have issues, please contact us for assistance.
