- The calendar control only supports dates.
The calendar control cannot be emptied by a user, as the date pickers on Android and iOS do not allow it. You can only set the value of a calendar to null again via K2 rules.
You can select the empty value as of version 1.5.
To set the date format, you can use the Style -> Format -> Date and Time section.
