Guide & best practices

Epoch Converter for Unix timestamps and dates

Convert between Unix time and human-readable dates – with seconds/milliseconds, UTC, local time and ISO 8601.

Typical use cases

Useful when debugging logs, APIs, database fields and tokens with timestamps (e.g. JWT exp/iat).

How Balou converts timestamps

Enter a timestamp or date; Balou converts locally and shows UTC, local time and ISO 8601 format.

Timestamp best practices

Mind seconds vs milliseconds, convert to UTC for comparisons and document the time zone explicitly.

Frequently asked questions

Seconds or milliseconds?

Unix seconds have 10 digits (e.g. 1718640000), milliseconds 13 digits (e.g. 1718640000000); mind the right format.

How do I convert to UTC?

The converter shows UTC and local time in parallel; for comparisons and storage UTC is the safe choice.

What is ISO 8601?

A standardized date format like 2025-06-17T14:00:00Z that is unambiguous and easy to sort.

Are my inputs sent anywhere?

No, the conversion runs locally in the browser.
