Timezone Finder

Click anywhere on the world map to pick a location, or enter latitude/longitude manually. The tool estimates the timezone from the longitude (each 15° band corresponds to one hour offset from UTC).

About Timezone Detection

The Earth is divided into 24 time zones, each roughly 15 degrees of longitude wide. This tool calculates the approximate UTC offset from your coordinates. The highlighted band on the map shows the selected timezone boundary.

Note: This is an approximation. Actual timezone boundaries follow political borders rather than strict longitude lines. Some regions observe Daylight Saving Time which shifts the offset. For example, China uses UTC+8 across its entire territory despite spanning five geographic time zones.
