Free Online Unix Timestamp Converter

Convert Unix timestamps to human-readable dates in multiple formats, or parse any date string back to an epoch — entirely in your browser with a live current-time display.

Backend developers convert database epoch values to readable dates during debugging. API integrators check token expiry or log timestamps. Anyone troubleshooting time-zone bugs can compare UTC, ISO, and local formats side by side.

How to Use

Frequently Asked Questions

How does the tool tell seconds from milliseconds?

Numbers with 10 or fewer digits are treated as Unix seconds. Numbers with 11+ digits are treated as milliseconds. You can always enter a full ISO string to avoid ambiguity.

What date string formats are accepted?

Any format accepted by the JavaScript Date constructor — ISO 8601 (2024-06-10T12:00:00Z), RFC 2822, and most common locale formats.

Is the live clock accurate?

It reads from your device's system clock and updates every second. Accuracy depends on your system time.

What is the 2038 problem?

32-bit systems store Unix timestamps as signed integers, which overflow on 19 January 2038 at 03:14:07 UTC. 64-bit systems and modern software are not affected.
