Unix Timestamp Converter Online Free

Convert between human-readable dates and Unix timestamps.

Supports standard date formats like "2026-05-13 10:00:00"

Seamlessly Translate Between Human and Machine Time

While humans prefer dates in years, months, and days, computers prefer a single, continuous number representing elapsed time. Our Unix Timestamp Converter bridges this gap, allowing you to instantly translate an epoch value into a readable local date or convert a specific calendar event into a precise timestamp for your database or code.

Seconds vs Milliseconds

Standard Unix time is measured in seconds (10 digits for current dates). However, high-precision environments like JavaScript and Java often use milliseconds (13 digits). Our tool allows you to toggle between these units with a single click, ensuring you get the exact value your system requires.

Frequently Asked Questions

Simply enter your local date and time in the "Human Readable" field, and the tool will automatically calculate the equivalent Unix timestamp.
The converter will show an "Invalid Date" message if the timestamp is not a number or is outside the valid range for JavaScript dates.
