Timezone Converter

This tool converts dates and times between different time zones. You can input local time, ISO format, Unix timestamps, or time strings with time zone information, and quickly get the corresponding result in your target time zone.

Multiple common formats are supported:

• Local date time: "2026-05-22 12:00:00"
• ISO 8601 (no timezone): "2026-05-22T12:00:00"
• ISO 8601 (with timezone): "2026-05-22T12:00:00+08:00"
• Unix timestamp (seconds/milliseconds): "1621670400", "1621670400000"
• Time zone name: "2026-05-22 12:00:00 Asia/Shanghai"

The system determines the source time zone using the following priority:

• If the input includes an explicit time zone or UTC offset (e.g. +08:00 or Z), it will be used directly
• If the input contains a time zone name (e.g. Europe/Paris), it will be automatically detected
• Otherwise, the manually selected source time zone will be used as the default

The tool first parses the input into a standard Date object (a single absolute time point), then formats it separately in both the source and target time zones to ensure consistent representation of the same moment across regions.

No. The original input remains unchanged. The tool only generates different representations of the same time point in different time zones.

Yes. If the input includes a time zone name or UTC offset, the system will automatically detect and prioritize it, so manual selection of the source time zone is not required.

It is useful for cross-time-zone communication, meeting scheduling, log time analysis, system debugging, and any scenario where time needs to be converted across regions.

Yes. All parsing and conversion are performed locally in the browser. No time data is uploaded to any server, ensuring privacy and security.
