Unix Time Converter

Convert between Unix epoch timestamps and human-readable dates. Paste a Unix timestamp (seconds or milliseconds) and get the corresponding date in UTC and your local timezone. Or paste a date and get the Unix timestamp. Handles both 10-digit (seconds) and 13-digit (milliseconds) epoch values automatically.

What it does

▸Converts Unix epoch seconds (1705312200) to human-readable dates
▸Converts Unix epoch milliseconds (1705312200000) automatically
▸Converts human-readable dates back to Unix timestamps
▸Shows both UTC and local timezone for each conversion
▸Supports ISO 8601, RFC 2822, and custom date format output

Use cases

▸Converting a Unix timestamp from a log file to a readable date
▸Generating a Unix timestamp for an API request or cron job
▸Debugging timezone-related issues in timestamp handling
▸Converting between seconds and milliseconds epoch formats

How it works

Paste a Unix timestamp or a date string into the input pane

The tool auto-detects whether it's a timestamp or a date

The converted result appears instantly with UTC and local time

Copy the output for use in your code or documentation

Frequently asked questions

1Does it handle milliseconds?

Yes. The tool detects 13-digit numbers as millisecond timestamps and 10-digit numbers as second timestamps. Both are converted correctly to human-readable dates.

2What timezone does it use?

It shows both UTC and your local timezone. The Unix timestamp itself is always UTC-based, so the UTC display is the canonical interpretation. Your local time is shown for convenience.

3Can it convert a date to a Unix timestamp?

Yes. Paste a date in ISO 8601 format (2024-01-15T10:30:00Z) or a common date format, and the tool converts it to a Unix timestamp in both seconds and milliseconds.
