Unix timestamps represent time as the number of seconds (or milliseconds) since January 1, 1970 (the Unix epoch). Our Timestamp Converter makes it easy to convert between timestamps and human-readable dates. Enter a timestamp to see the corresponding date, or enter a date to get its timestamp. Select between seconds and milliseconds, and choose a timezone for the output. The tool also shows the current Unix timestamp at the bottom for reference, updating in real-time so you always have the latest value for testing, comparison, or integration with your applications. This is essential for debugging time-related issues in APIs, working with databases that store timestamps as integers, or converting dates between different systems and programming languages. The converter handles both 10-digit (seconds) and 13-digit (milliseconds) timestamps correctly. You can copy the converted value with a single click, making it easy to use in your code, configuration files, or documentation for your team and stakeholders. All conversions happen locally in your browser — your data never leaves your device. This makes it safe to use with sensitive timestamps from user data, proprietary systems, or confidential business logic.

FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (the Unix epoch). It's a standard way to represent time in computing.
Seconds vs milliseconds?
Unix timestamps are traditionally in seconds (10 digits). JavaScript and many modern systems use milliseconds (13 digits). Our converter handles both.
What timezone is used?
The converter supports multiple timezones. By default it shows UTC. You can select your preferred timezone from the dropdown.
