Convert between Unix timestamps and human-readable dates instantly
A Unix timestamp, also known as Epoch time or POSIX time, is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This standardized format is widely used in computing, databases, and programming to represent specific moments in time in a universal, timezone-independent way.
Our Unix Timestamp Converter is a free online tool that allows you to instantly convert between Unix timestamps and human-readable dates. Whether you're a developer debugging code, a system administrator managing logs, or simply curious about how timestamps work, this tool provides accurate conversions with support for both seconds and milliseconds.
Converting Unix Timestamp to Date: Simply paste your Unix timestamp (in seconds or milliseconds) into the input field and click "Convert to Date". The tool will instantly display the corresponding date and time in multiple formats including local time, UTC, ISO 8601, and a human-friendly relative time format.
Converting Date to Unix Timestamp: Use the date and time picker to select your desired date and time, choose your timezone preference, and click "Convert to Timestamp". The tool will generate both the seconds and milliseconds versions of the Unix timestamp.
Current Timestamp: The current Unix timestamp is displayed at the top and updates every second. You can copy it directly to your clipboard with a single click.
Unix timestamps are the foundation of time representation in most programming languages and systems. They provide a simple, unambiguous way to represent any point in time as a single number. This makes them ideal for storing dates in databases, comparing times, and performing time-based calculations.
The Unix epoch (January 1, 1970, 00:00:00 UTC) was chosen as the reference point for Unix timestamps. Any timestamp before this date is represented as a negative number, while timestamps after are positive. Most modern systems use 32-bit or 64-bit integers to store timestamps, allowing representation of dates far into the future.
Unix timestamps can be expressed in seconds or milliseconds. The seconds version is the standard Unix timestamp, while the milliseconds version (often called Unix time in milliseconds) provides greater precision. Most modern applications use milliseconds for better accuracy, especially in high-frequency trading, real-time analytics, and performance monitoring.
To convert between the two: multiply seconds by 1000 to get milliseconds, or divide milliseconds by 1000 to get seconds. Our converter handles both formats automatically.
One of the key advantages of Unix timestamps is that they are timezone-independent. A Unix timestamp always represents the same moment in time, regardless of the observer's timezone. However, when converting to human-readable dates, the timezone matters for display purposes. Our tool automatically detects your local timezone and provides conversions in both local and UTC formats.
The current Unix timestamp is displayed at the top of this tool and updates every second. As of now, it's continuously increasing. You can copy it with a single click for use in your applications.
Simply copy the timestamp value from your log file and paste it into the "Unix Timestamp to Date" field. If your logs use milliseconds, the tool will automatically detect and handle that. Click "Convert to Date" to see the human-readable date and time.
Yes! When converting a date to a Unix timestamp, you can select whether you want to interpret the date in your local timezone or UTC. The resulting timestamp will be the same regardless, but the interpretation of the input date will differ based on your selection.
Unix time is a single number representing seconds (or milliseconds) since the epoch. ISO 8601 is a human-readable format like "2024-01-01T12:00:00Z". Both represent the same moment in time but in different formats. Unix time is better for storage and calculations, while ISO 8601 is better for human readability.
Unix timestamps can represent any date from December 13, 1901 (negative timestamps) to January 19, 2038 (for 32-bit systems) or much further for 64-bit systems. Most modern systems use 64-bit timestamps, allowing representation of dates billions of years in the past and future.
This is likely due to timezone differences. Unix timestamps are always in UTC, but when displayed as a local time, they're adjusted for your timezone. Make sure you're interpreting the "Local Time" result correctly for your timezone, or use the "UTC Time" result for a timezone-independent view.
