Additional Information

Technical Details

This plugin uses the ECMAScript Internationalization API (Intl) for client-side date formatting. The Intl API provides robust support for various calendar systems and locales. For older browsers that may not fully support all features, the plugin includes fallback formatting options.

Browser Compatibility

Modern browsers (last 2-3 years) fully support the plugin’s functionality. For older browsers, basic date formatting will still work, but some advanced calendar systems might fall back to Gregorian.

Privacy

This plugin does not collect or share any personal data, and all date formatting is done client-side in the user’s browser.
