calcuate days in a calender.era or between two days

[aminur rashid]

Hi,
I have two Date Instance
Date startDate and Date endDate.
Now user will be specifying some step size to go from startDate to endDate in a JSpinner.
Now i have to validate that the step size should be less than the number of days between startDate and endDate.
e.g
startDate is 05/01/2000 // in dd//MM/yyyy format
and endDate is 05/02/2000 //in same format
Now i should stop user from selecting step size as Calendar.Era,Calendar.Year but should allow him to select lower values.
Any idea how to proceed??
