Unix timestamp converter. Epoch ↔ date.

Convert between Unix time and readable dates

A Unix timestamp (a.k.a. epoch time) counts the seconds since 1 January 1970 UTC. It’s how computers, logs, APIs and databases store time — compact and unambiguous, but unreadable to humans. This tool converts either direction, right in your browser.

How to use it

• Have a timestamp? Paste it (seconds like 1735689600, or milliseconds) and get the UTC, local and ISO 8601 dates.
• Have a date? Type it (e.g. 2026-01-15 or 2026-01-15T09:30:00Z) and get the Unix timestamp in seconds and milliseconds.

Mynify detects which you entered and shows all the useful forms — copy any of them with one click.

When it’s handy

• Reading logs and API responses that store epoch time.
• Debugging date handling in code.
• Scheduling and configs that expect a Unix timestamp.
