About this tool.
Paste a Unix timestamp (seconds or milliseconds) or any common date string, and see it rendered as ISO 8601, RFC 2822, UTC, local time, the weekday, and a relative time from now. Numeric input is auto-classified by magnitude, and if it could be either seconds or milliseconds, the alternative is shown alongside.
