Maximum date (date_max) (New in 2.05 )
Description
This question attribute can be used to set the maximum value for the calendar question. It applies to both, the popup-variant of the calendar and the dropdown fields.
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 maximum date can be dynamically calculated. For example, you can use a date from a previous answer + 4 weeks as a maximum for the present question by entering: date("Y-m-d H:i",strtotime(departuredate)+4*60*60*24*7).
