Timestamp Converter

Convert between Unix timestamps and human-readable dates in any timezone.

Convert between Unix timestamps and human-readable dates in any timezone.

Quick start: Enter a Unix timestamp (seconds or milliseconds) to convert it to a human-readable date and time. → Alternatively, pick a date and time using the date picker to get the corresponding Unix timestamp. → Select your timezone from the dropdown to see the conversion in your local time or any other zone.

Why use Timestamp Converter?

  • Converts in both directions — Unix timestamp to date and date to Unix timestamp.
  • Auto-detects whether the input is in seconds or milliseconds, so you do not need to guess.
  • Full timezone support lets you convert to and from any timezone, not just UTC.
  • Runs entirely in your browser with no data sent to any server.

Common use cases

  • Debug log timestamps from server logs, database records, or API responses by converting them to readable dates.
  • Generate Unix timestamps for scheduling features, cron jobs, or time-based API parameters.
  • Compare timestamps across different time zones to diagnose timezone-related bugs.
  • Convert human-readable dates to Unix time for database queries and scripting.

About Timestamp Converter

Unix timestamps are the universal time representation in software, but they are unreadable to humans — 1713100800 means nothing at a glance. Xevon Tools' Timestamp Converter bridges this gap by converting Unix timestamps to human-readable dates and vice versa. The tool auto-detects whether your input is in seconds or milliseconds, supports all IANA timezones through the browser's Intl API, and handles edge cases like negative timestamps for pre-1970 dates. Conversion works in both directions: paste a Unix timestamp to see the date, or pick a date to get the timestamp. This is invaluable for debugging server logs, diagnosing timezone bugs, generating timestamps for API parameters, and understanding time values in database records. The output includes both ISO 8601 format for technical use and a human-friendly format for quick reading. Everything runs in your browser with no server requests, making it safe to convert timestamps from production systems.

Frequently asked questions

Yes. The tool examines the length of the input number to determine whether it is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly.
All IANA timezones are supported through the Intl API built into your browser. You can select any timezone from the dropdown to see the conversion in that zone.
Yes. Negative Unix timestamps represent dates before January 1, 1970 (the Unix epoch). The tool converts these correctly to their corresponding historical dates.
The tool displays the date in ISO 8601 format (YYYY-MM-DDTHH:mm:ss) as well as a human-friendly format. The Unix timestamp output is a plain integer in seconds.
