Count days between dates

Hello i have a table with 2 dates (format d-m-yyyy h:mm:s, example: 3-12-2007 9:05:03)
Is it possible to get the days between those dates?

I have the following table:

date1                            date2
------------------------     ---------------------
2-12-2007 23:00:00     3-12-2007 9:06:38
1-12-2007 10:24:23     3-12-2007 9:06:38
4-12-2007 23:00:00     10-12-2007 9:06:38
2-12-2007 23:00:00     15-12-2007 10:24:23
2-12-2007 10:24:23     15-12-2007 9:06:38

I want the result like below

date1                            date2                            days
------------------------     ---------------------         -----
2-12-2007 23:00:00     3-12-2007 9:06:38          1
1-12-2007 10:24:23     3-12-2007 9:06:38          2
4-12-2007 23:00:00     10-12-2007 9:06:38        6
2-12-2007 23:00:00     15-12-2007 10:24:23    13
