Complete guide to using Epoch Converter — a free online tool by akousa.net.
Get started in seconds — no signup required
The Epoch Converter translates between Unix timestamps — the number of seconds or milliseconds elapsed since the Unix epoch (January 1, 1970 00:00:00 UTC) — and human-readable ISO 8601, RFC 2822, and locale-formatted dates across any timezone. Unix timestamps are the universal time representation used in databases, JWT expiration claims, log files, Linux and macOS filesystems, and virtually every programming language standard library. This tool handles both 10-digit second-precision and 13-digit millisecond-precision timestamps with automatic detection.

Enter a Unix timestamp — seconds or milliseconds, auto-detected — to see the corresponding UTC date, local date, and dates in multiple named timezones simultaneously. Alternatively, use the date-time picker or type an ISO 8601 string to convert it to its epoch value. The result includes the epoch in both seconds and milliseconds, plus a relative time label like '3 hours ago' or 'in 2 days' for quick context.
