Unix Timestamp Converter

Convert Unix timestamps into readable dates and any date back into a timestamp. The tool auto-detects seconds versus milliseconds, shows both UTC and your local time, and renders the ISO 8601 string alongside a relative 'time ago' value. A live clock makes it easy to grab the current timestamp on demand.

• Convert timestamp to date and date to timestamp in one place
• Auto-detects seconds vs. milliseconds and lets you override the unit
• Shows UTC, local time, ISO 8601, and a relative 'time ago' value
• Live current Unix time with a one-click 'use now' button
• Handles negative timestamps for dates before 1970
• Copy any representation instantly

1. 1

   Enter a timestamp or a date

   Paste a Unix timestamp to convert it to a date, or pick a date and time to get its timestamp. The tool detects whether your number is in seconds or milliseconds.

2. 2

   Review the conversions

   See the value in UTC and local time, as an ISO 8601 string, and as a human-friendly relative time.

3. 3

   Copy what you need

   Copy the timestamp, the ISO string, or a formatted date to use in code, logs, or a database query.

• Reading epoch timestamps found in logs, JSON, and databases
• Interpreting JWT exp, iat, and nbf claims as real dates
• Building date filters for queries and API requests
• Debugging time zone bugs by comparing UTC and local output
• Grabbing the current Unix time for seeding or testing
