About this tool
Unix timestamps (epoch time) are the standard way computers track time — counting seconds since January 1, 1970. Developers, database administrators, and system engineers work with timestamps daily when debugging logs, querying databases, or building APIs.
This converter handles both second and millisecond precision timestamps, shows multiple date formats including ISO 8601, and provides a live relative time display. All conversions happen in your browser with zero server calls.
About this tool
The Timestamp Converter lets you convert Unix timestamps (seconds since January 1, 1970 UTC) into human-readable dates in multiple formats including ISO 8601, local time, UTC, and relative time. You can also convert any date back into a Unix timestamp.
This tool is essential for developers working with APIs, databases, or logs that use epoch timestamps. Everything runs locally in your browser — no data is ever sent to a server.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It's widely used in programming, databases, and APIs to represent dates.
Does this tool handle millisecond timestamps?
Yes. The converter automatically detects whether your input is in seconds or milliseconds and converts accordingly. Timestamps with 13+ digits are treated as milliseconds.
What date formats are shown?
The converter shows your timestamp in ISO 8601, local time, UTC, and relative format (e.g., '2 hours ago'). You can copy any format with one click.
