About the tool

🕒 Timestamp Converter – Convert Between Unix Timestamps and Human-Readable Dates

The Timestamp Converter is a client-side tool that allows you to convert between Unix timestamps (epoch time) and human-readable date formats in both directions. Whether you're a developer, data analyst, or anyone working with time data, this tool makes it easy to convert timestamps without sending any data to a server.

This guide explains what Unix timestamps are, their formats, and walks you through using our free online converter for your projects.

📘 What are Unix Timestamps?

A Unix timestamp (also known as epoch time, POSIX time, or Unix time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This point in time is known as the Unix epoch.

Unix timestamps are widely used in programming and computing because they provide a standardized way to represent time across different systems and programming languages. They're particularly useful for:

  • Storing dates and times in databases
  • Calculating time differences
  • Sorting events chronologically
  • Handling time across different time zones

🧩 Timestamp Formats

Unix timestamps are commonly represented in two formats:

  • Seconds: The traditional Unix timestamp counts seconds since the epoch. Example: 1623456789
  • Milliseconds: Many modern systems use milliseconds for greater precision. Example: 1623456789000

Our converter handles both formats automatically, detecting whether a timestamp is in seconds or milliseconds based on its length.

⚙️ How the Timestamp Converter Works

Our Timestamp Converter provides a simple interface to:

  1. Convert Unix timestamps to human-readable dates in various formats
  2. Convert human-readable dates to Unix timestamps in seconds or milliseconds
  3. View conversions in real-time as you type or select dates
  4. Copy results with a single click
  5. Set the current time with the "Now" button

🧩 Key Features

  • ⚡ Real-time conversion as you type or select dates
  • 🔄 Bidirectional conversion (timestamp ↔ date)
  • 🌐 Support for multiple time zones
  • 📋 Easy copying of conversion results
  • 🕒 "Now" button to quickly set current time
  • 🔢 Support for both seconds and milliseconds
  • 📅 Multiple date/time formats (ISO 8601, RFC 2822, etc.)
  • 🔐 Client-side only — all conversion happens in your browser
  • 📱 Mobile and desktop-friendly interface
  • 🌓 Light and dark mode support

🔐 Security and Privacy

Our Timestamp Converter runs entirely in your browser using JavaScript's native Date object, ensuring:

  • No server communication — your data never leaves your device
  • No tracking or logging of your conversions
  • Fast performance with instant results

🔄 Common Uses for Timestamp Conversion

Timestamp conversion is useful in many scenarios:

  • Debugging applications that use timestamps
  • Reading log files that contain Unix timestamps
  • Working with APIs that return timestamps
  • Database queries involving time data
  • Analyzing time-series data in various formats

🔄 How to Use the Timestamp Converter

  1. Enter a Unix timestamp or select a date/time using the date picker
  2. View the conversion results in real-time
  3. Toggle between seconds and milliseconds for timestamp output
  4. Select different date formats and time zones as needed
  5. Use the "Now" button to quickly set the current time
  6. Copy the results using the copy buttons

Frequently Asked Questions

  • Is the Timestamp Converter free ?

    Yes, Timestamp Converter is totally free :)

  • Can i use the Timestamp Converter offline ?

    Yes, you can install the webapp as PWA.

  • Is it safe to use Timestamp Converter ?

    Yes, any data related to Timestamp Converter only stored in your browser(if storage required). You can simply clear browser cache to clear all the stored data. We do not store any data on server.

  • What is a Unix timestamp?

    A Unix timestamp (also known as epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It's a way to track time as a running total of seconds, which makes it easier for computers to process and compare dates.

  • Why use Unix timestamps?

    Unix timestamps are widely used in programming because they're simple, language-agnostic, and make date/time calculations straightforward. They avoid complications with time zones, daylight saving time, and calendar differences.

  • What's the difference between seconds and milliseconds in timestamps?

    Unix timestamps traditionally count seconds since the epoch (January 1, 1970). However, many modern systems use milliseconds for greater precision. A millisecond timestamp is 1000 times larger than its second equivalent (e.g., 1623456789000 ms vs. 1623456789 s).

  • How does this Timestamp Converter work?

    This tool converts between Unix timestamps and human-readable dates in both directions. It can handle timestamps in seconds or milliseconds, and can display dates in various formats including local time, UTC, ISO 8601, and RFC 2822. All conversion happens client-side in your browser.

  • What time zone is used for the conversions?

    By default, the tool shows both your local time zone and UTC (Coordinated Universal Time). You can also select specific time zones for the conversion using the time zone selector.
