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.

How to Use

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.

Common Use Cases

• •Backend developers converting ISO 8601 datetime strings to the exact format expected by REST API request bodies, query parameters, or database INSERT statements
• •Frontend engineers formatting UTC API timestamps into locale-aware display strings like 'March 18, 2026' or '18/03/2026' for different regional user interfaces
• •Data analysts generating human-readable date labels for chart axes, report titles, or dashboard widgets from raw numeric Unix timestamp columns
• •Developers testing date-parsing edge cases by producing dates in multiple formats including leap days, DST transitions, and year-boundary values
• •Technical writers and documentation engineers formatting release dates, changelog timestamps, and version histories consistently across ISO and locale-specific conventions
