How sizes are measured

The JavaScript figure includes this component’s required helpers. CSS includes its styling dependencies. Each entry is bundled separately for ES2022, minified, then compressed with gzip level 9. Your bundler may share helpers across components. Images, fonts, examples and application code are excluded.

Before compression: JavaScript 25.7 KiB; component CSS 8.0 KiB. These figures describe browser assets, not the complete package download.

Type a date or open the calendar. Arrow keys move between dates; month and year selectors jump directly. Escape closes and restores focus.

createDatePicker

Value, Min, Max and DisabledDates use YYYY-MM-DD. DateFormat changes typing/display only. Handle Change to retain the selected value. Empty is allowed unless IsRequired is true. The calendar uses the application locale for month and weekday names.
