Timestamp & Date Converter

Convert any timestamp or date between Unix (s/ms), ISO 8601, RFC 2822, and human-readable — in any timezone — with relative time and calendar info.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

• Every format at once: unixSeconds, unixMillis, iso8601, rfc2822, utcString.
• Smart parsing: Unix seconds vs milliseconds auto-detected by magnitude; ISO / RFC / date strings; or the literal "now".
• Any timezone: timezoneFormatted rendered for any IANA zone (e.g. America/New_York) via Intl.
• Calendar context: dayOfWeek, dayOfYear, ISO weekNumber, isLeapYear.
• Relative time: relativeFromNow ("in 2 hours", "3 days ago", "now").
• Single value or bulk array in one run.

Built for logs, scheduling agents, and anywhere a timestamp needs to be normalized.

Input

{
  "input": "1516239022",
  "timezone": "America/New_York"
}

Or convert many at once:

{ "inputs": ["now", "2018-01-18T01:30:22Z", "1700000000000"], "timezone": "UTC", "maxItems": 50 }

Output

  "unixMillis": 1516239022000,
  "iso8601": "2018-01-18T01:30:22.000Z",
  "rfc2822": "Thu, 18 Jan 2018 01:30:22 GMT",
  "utcString": "Thu, 18 Jan 2018 01:30:22 GMT",
  "timezoneFormatted": "Wed, Jan 17, 2018, 20:30:22 EST",
  "dayOfWeek": "Thursday",
  "dayOfYear": 18,
