Basically, i want the participants to be allowed only to enter dates between december 10, 2012 and december 24, 2012. Unfortunately there are no minimum/maximum fields for the date question.
How can I use expression manager to check if a entered date is smaller or larger than a given date? Are there any examples I could have a look at?
This has been implemented in version 2.05.
You'll find min max fields in the advanced question attributes of the date question. Have a look in the manual for details.

Had to make myself more clear, sorry.
I would like to calculate the minimum and maximum dates.
If someone gives his date of birth and I want to know how long someone has lived in a city, I don't want them to be able to pass a date before their dob or after today.
Try the following: in the datemin field put your questioncode of the question that asks for the date of birth. Eg. Dob
In the maxdate field put:date("Y-m-d H:i",strtotime("now"))
