About Timestamp Converter

A Unix timestamp converter is an essential tool for developers, system administrators, and anyone working with logs or APIs. This free browser-based converter instantly transforms Unix timestamps (also called epoch time) into human-readable dates and back again. Whether you're debugging server logs, analyzing API responses, or checking database records, converting between epoch timestamps and standard date formats is a common task that doesn't require any signup or installation.

Unix timestamps represent the number of seconds (or milliseconds) since January 1, 1970 UTC. Converting epoch to date helps you understand when events happened in your systems, while the reverse conversion lets you calculate exact Unix timestamps for specific dates. This tool handles both directions instantly, supporting standard Unix timestamps and millisecond-precision variants, making it useful for working with nearly any modern API or logging system.

Because this tool runs entirely in your browser, your timestamps are never sent anywhere—they stay on your device. It's completely free with no accounts needed, so you can bookmark it and use it whenever you need to convert a timestamp. Whether you're dealing with a single timestamp or batch converting multiple values, you'll get instant results without waiting for server processing.

Popular uses

  • ✦ Debug server logs by converting timestamps to readable dates and understanding when errors or events occurred
  • ✦ Work with REST APIs that return data with Unix timestamps by instantly converting them to check dates
  • ✦ Analyze database query results that include epoch timestamps without manually calculating or researching conversion formulas
  • ✦ Set up date range filters in monitoring tools or log analyzers by converting your target dates into Unix timestamps
  • ✦ Check the creation or modification dates of files and records in systems that only expose epoch time values

Frequently asked questions

What exactly is a Unix timestamp?
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have passed since January 1, 1970 at midnight UTC. It's a standard way for computers to represent dates and times as a single number, making it easy for systems to store, compare, and calculate time differences without dealing with time zones or calendar complexities.
How do I convert a Unix timestamp to a date?
Paste your Unix timestamp into the converter and it will instantly show you the corresponding date and time. The tool automatically detects whether you've entered seconds (10-digit numbers like 1640995200) or milliseconds (13-digit numbers like 1640995200000) and converts accordingly.
Can I convert a date back to a Unix timestamp?
Yes. Enter a date, time, and timezone into the converter and it will calculate the exact Unix timestamp for that moment. This is useful when you need to set date filters in databases, APIs, or log analysis tools that accept epoch time as input.
Is this tool secure and private?
Completely. Everything happens in your browser—no data is sent to any server. Your timestamps are never stored, logged, or transmitted anywhere. You can safely use this tool for sensitive timestamps from internal systems without any privacy concerns.
Is Timestamp Converter free to use?
Timestamp Converter is 100% free — no signup, no watermarks and no usage limits. It’s one of 200+ free tools we build and give away.
How accurate are the conversions?
Conversions use exact, standard ratios and update live as you type — accurate to many decimal places.
