Accessibility

On mobile, a date picker should allow users to enter dates manually by inputting text, without using the picker. This interaction allows multiple input methods and makes it accessible to those using assistive technology.

• On desktop, the text field can be used for input.
• On mobile, the input picker should be available from the calendar pickers via the edit icon.

Touch targets

Touch targets for mobile date pickers should be as large as possible, filling the available space. The minimum touch target size for a date picker is 32 x 32dp.

The edit icon indicates the ability to switch to the mobile input picker.

On the mobile date range picker, touch targets are maximized at 48 x 48dp.
