Date Format

The date format attribute can be used to specify dynamically how the date value of the property should be formatted and validated in modeled dialogs. It is defined by using certain pattern letters (see the table below) and optional separators.


A date value can be created by clicking on the choose date button on a modeled input dialog with a date field. The date will be generated with the specified format. If the date format contains time pattern letters (like “h” for hours), the current time will be used for the generated date.

If a user chooses to type the date in manually, the dialog will validate the field with the specified date format. The following table shows all available date format pattern letters (all other characters from “A” to “Z” (lower and upper case) are reserved):
