| Event | Unix Timestamp | UTC Date |
|---|
A Unix timestamp (also called Epoch time) counts the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 — ignoring leap seconds. It's the standard way computers store and compare points in time internally, since it's just a single number rather than a formatted string.
Many systems use milliseconds instead of seconds (multiply by 1000), which is common in JavaScript (Date.now()) and many JSON APIs. This tool supports both.
The Timestamp Converter is a fast, free, and easy-to-use online tool that helps you convert Unix timestamps into human-readable dates and convert dates back into Unix timestamps instantly. Whether you're working with APIs, databases, server logs, or application debugging, this tool provides accurate timestamp conversion in just a few clicks.
It supports Unix timestamps in both seconds and milliseconds, automatically detects your local timezone, and provides multiple output formats including UTC time, ISO 8601, and localized date/time. Developers can also convert multiple timestamps simultaneously using the built-in Batch Converter.
The live Unix Timestamp section continuously displays the current Unix time in real-time. This is useful when generating timestamps for APIs, authentication tokens, logging systems, scheduling applications, or testing software that relies on Unix Epoch values.
Simply enter any Unix timestamp to instantly convert it into a readable date and time. The converter automatically detects whether the timestamp is in seconds or milliseconds and provides accurate results without requiring any manual calculations.
The conversion results include:
Need to generate a Unix timestamp from a specific date? Simply choose a date, select the time, and pick the desired timezone. The tool instantly generates both Unix timestamps in seconds and milliseconds.
Additional output formats include:
Convert multiple timestamps or dates simultaneously using the Batch Converter. Paste one timestamp or date per line, and the tool automatically detects the input format before converting each entry. This feature is especially useful for developers working with log files, analytics reports, exported databases, and API responses.
Save time using built-in Quick Actions. Instantly populate the converter with commonly used timestamps, including:
These shortcuts eliminate manual date selection and speed up common development tasks.
The converter automatically detects your browser's local timezone and displays the corresponding UTC offset. You can also select a different timezone to compare timestamps across regions, making it useful for global applications and distributed systems.
The built-in reference table provides several well-known Unix timestamps, including the Unix Epoch, Y2K, the beginning of recent years, and important timestamp limits. These references are helpful for learning, testing, and verifying timestamp calculations.
Unlike basic timestamp converters, this tool combines live Unix time, bidirectional conversion, batch processing, timezone support, ISO formatting, quick shortcuts, and automatic timezone detection in a single interface. Everything runs instantly in your browser, making it one of the fastest and most convenient timestamp conversion tools available for developers and technical users.
