Unix Timestamp Converter
Di Unix Timestamp Converter
Our free online Unix Timestamp Converter converts a Unix timestamp (in seconds or milliseconds) into a human-readable date in both your local timezone and UTC, and converts any date back into its timestamp.
Timestamp → Date
Date → Timestamp
A live-updating display also shows the current Unix timestamp in real time - handy for developers working with APIs, logs, or databases that store time as epoch seconds.
Who Uses This Tool
Backend developers use it to quickly translate a timestamp seen in an API response or database row into a readable date while debugging. DevOps engineers scanning server logs use it to convert epoch values into local time to line up an incident with other events. QA testers use it to generate a specific future or past timestamp for testing date-dependent logic. Anyone integrating with a third-party API that returns epoch time uses the live current-timestamp display as a quick reference point. Because it shows both local time and UTC side by side, it also helps catch timezone-related bugs that are easy to miss when only one timezone is displayed. It handles both second-based and millisecond-based epoch values, which matters since different APIs and languages default to different units and mixing them up silently produces a date decades off from what was intended.

Frequently asked questions
What is a Unix timestamp?
The number of seconds (or milliseconds) elapsed since midnight UTC on January 1, 1970 (the "Unix epoch") - a compact, timezone-independent way of representing a moment in time, widely used in programming, databases, and APIs.
Why do I need to specify seconds vs. milliseconds?
Most Unix/Linux systems and databases use seconds, while JavaScript's Date object and many web APIs use milliseconds - picking the wrong unit will convert to a wildly different date, so this tool lets you choose explicitly.
Does this account for my timezone?
The "Date → Timestamp" conversion uses your browser's detected local timezone; the resulting timestamp itself is always timezone-independent (UTC-based), which is the whole point of Unix time.
