Timestamp Converter

Paste a Unix timestamp or a date in almost any format and see it as Unix seconds and milliseconds, ISO 8601, RFC 2822, IST and UTC.

What is the Timestamp Converter?

Different systems represent time differently. This converter translates between the most common representations.

How does it work?

Numeric input is treated as a Unix timestamp (unit detected by length). Text is parsed as ISO 8601 or RFC 2822. The instant is then formatted in every representation.

Example

2026-09-27T10:30:00+05:30 is Unix 1790485200 and 2026-09-27T05:00:00.000Z in ISO UTC.

Frequently asked questions

Is my data sent to a server?

No. This tool runs entirely in your browser; nothing you paste is uploaded or stored.

Which date formats are accepted?

ISO 8601 (recommended), RFC 2822 (e.g. “Sun, 27 Sep 2026 05:00:00 GMT”) and Unix timestamps. Ambiguous formats like 03/04/2026 are not reliable.
