Date Format Converter
Convert dates between the most common formats (YYYY-MM-DD, MM/DD/YYYY, DD/MM/YYYY), ISO 8601, and Unix timestamp, with automatic detection of the input format. Everything is calculated in your browser, with no data sent to a server.
How it works
- Type or paste the date you want to convert (or use the built-in example).
- Choose the input format, or leave it on 'Auto-detect' so the tool identifies it for you.
- Select the output format you want, including ISO 8601 or Unix timestamp.
- The result updates instantly as you change the date or the formats.
- Copy the result with one click.
Use cases
- Convert a form date (DD/MM/YYYY) into the ISO 8601 format an API expects.
- Turn a Unix timestamp stored in a database into a readable date.
- Adapt dates exported from a spreadsheet to the format another system needs.
- Quickly check what date a specific Unix timestamp corresponds to.
