About this tool
The Unix Timestamp Converter is an essential tool for developers and system administrators. Unix time (also known as Epoch time) is the number of seconds that have elapsed since January 1, 1970 (UTC), minus leap seconds. It is widely used in operating systems, databases, and file formats.
Our tool solves the common confusion between seconds and milliseconds. If you paste a 13-digit number, we smart-detect it as milliseconds (JavaScript standard). If it is 10 digits, we treat it as seconds (Unix standard). We even handle microseconds and nanoseconds for high-precision logs.
You can easily convert a human-readable date (like "2024-12-31 23:59:00") back into a raw timestamp for use in your code or SQL queries. All conversions happen locally in your browser.

How to use
- To convert a timestamp: Enter the number in the "Timestamp" field.
- The tool automatically detects if it is in seconds, milliseconds, etc.
- To convert a date: Enter the date and time in the "Human Date" section.
- Click "Convert" to see the equivalent timestamp and formatted dates.
- Use the "Current Time" button to get the current Unix timestamp.
Benefits
- Bi-directional conversion (Timestamp ↔ Date)
- Auto-detection of Seconds vs Milliseconds
- Displays Local TimeConfig, UTC, and ISO 8601
- Shows relative time (e.g., "5 minutes ago")
- Clean interface for developers
- One-click copy for all outputs
- Handles future and past dates accurately
FAQs
What is a Unix Timestamp?
A Unix timestamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Therefore, the Unix time stamp is merely the number of seconds between a particular date and the Unix Epoch.
Why does my timestamp have 13 digits?
A 13-digit timestamp usually represents milliseconds (1/1000 of a second). This is common in JavaScript (Date.now()) and Java. Standard Unix timestamps are 10 digits (seconds).
Does this handle Timezones?
Yes! The tool displays both the UTC (Coordinated Universal Time) and your Local Time based on your browser settings. When converting from a date, you can specify if the input is UTC or Local.
What is the Year 2038 problem?
On January 19, 2038, 32-bit systems will run out of numbers to store the Unix timestamp (it will exceed 2,147,483,647). Systems must remain upgraded to 64-bit to avoid this issue.
How do I get the current Unix timestamp?
Click the "Current Time" button in the tool, or use Date.now()/1000 in JavaScript, time() in PHP, or time.time() in Python. The current timestamp is useful for logging events, measuring durations, and timestamping data.
Can I convert timestamps before 1970?
Yes! Negative Unix timestamps represent dates before January 1, 1970. For example, -86400 represents December 31, 1969. This tool correctly handles both positive (future/recent) and negative (historical) timestamps.
