How to Use Date Formatter

What is Date Formatter?

The Date Formatter converts any date into over a dozen output patterns including ISO 8601, RFC 2822, RFC 3339, Unix timestamps, locale-specific formats, and fully custom token-based patterns like YYYY-MM-DD HH:mm:ss. It uses moment.js-compatible format tokens, making output directly usable in applications that rely on that formatting syntax. This tool is indispensable for developers, data engineers, and technical writers who work across APIs, databases, and front-end displays that each expect different date string representations.

Features

How do I use Date Formatter?

Enter a date by typing it, pasting a timestamp, or using the date-time picker — the tool auto-detects most common input formats. Select a predefined format preset or build a custom pattern using tokens like YYYY (4-digit year), MM (month), DD (day), HH (24-hour), hh (12-hour), mm (minutes), ss (seconds), and Z (timezone offset). The formatted result updates instantly and can be copied with one click or downloaded as a text snippet.
