Minimum date (date_min) (New in 2.05 )
Description
This question attribute can be used to set the minimum value for the date question. It applies to both, the popup-variant of the calendar and the dropdown fields. Besides validation via Expression Manager, the slection of days in the popup calender is also limited accordingly.
Valid values
- Any date value in format YYYY-MM-DD (eg., 2013-08-24)
- Any year value
- Reference to another date/time question(eg., dateofbirth)
- Expressions With expressions, a minimum date can be dynamically calculated. For example, you can use a date from a previous answer + 3 days as a minimum for the present question by entering: date("Y-m-d H:i",strtotime(departuredate)+3*60*60*24).
