Unix Timestamp Converter — Epoch to Human Date
Convert between Unix epoch timestamps and human-readable dates. Supports both seconds and milliseconds. Type in either field and the other updates instantly.
How to Use the Timestamp Converter
Type a Unix timestamp (in seconds or milliseconds) into either field, or type a human-readable date into the date field. All values update instantly. Use the "Now" button to capture the current time, or "Today at Midnight" for the start of today.
This tool is essential for developers working with databases, APIs, log files, and any system that uses Unix epoch time. It supports both seconds (standard Unix) and milliseconds (JavaScript Date).
Frequently Asked Questions
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds. It is widely used in programming and databases.
To convert a Unix timestamp to a date, multiply the timestamp by 1000 (to convert seconds to milliseconds) and pass it to JavaScript's Date() constructor. Our tool does this instantly as you type.
The Year 2038 problem is that many systems store timestamps as a signed 32-bit integer, which can only represent dates up to January 19, 2038. After that, timestamps will overflow and wrap around to negative numbers.
Unix timestamps are typically measured in seconds since epoch. JavaScript uses milliseconds (1000x seconds). Our converter handles both — just paste your value and it auto-detects. A millisecond timestamp has 13 digits vs 10 digits for seconds.
