Sizes M and L/XL
The date/time picker appears as a popover when the user clicks or taps a date (input field) on the calendar, The user can then select the desired date from the calendar, and the time from the rotating wheel.
When the user clicks or taps the OK button, the popover closes and the selected date and time appear in the input field. When the user selects Cancel, the action is aborted and the input field remains unchanged.
Size S and Mobile Size
On smaller devices, the user can choose the date and time value in arbitrary order by tapping the segmented button on top of the screen. Be aware that the popover is superimposed on the input field during the selection process for mobile/S sizes.
The user can select the desired date from the calendar, and the time from the rotating time wheel. Clicking a date in the calendar automatically leads the user to the time selection screen.
When the user selects OK, the popover closes and the selected date and time appear in the input field. When the user selects Cancel, the action is aborted and the input field remains unchanged.
Date Picker and Time Picker
In general, we recommend separating the date/time picker controls as the time picker supports the mask input function and the date picker allows the user to enter date in different formats. This makes it easier and more convenient for the user to enter the desired values. For additional guidelines and information on the individual controls, see the resources section below.
Independently of the chosen control, set the default values of the date/time picker carefully to avoid unnecessary scrolling. It often makes sense to set the default for the time to the full or half hour, setting the minutes to 00 or 30. Sometimes, it may also make sense to use the current time and date.
