Hello

How do I get the difference in numbers between two dates?

I have tried using "Difference fro previous period", but It does not work with days?

Please look at Excel spreadsheet column "C"

Thanks

If you just want straight no of days just use minus.

SAS stores dates as counts of days (from a given starting point, which is 1960-01-01). The difference in days between two dates can therefore be calculated with a simple subtraction.

I have not got it to work in 7.4 but in 8.2 it works by using relative period and set offset to -1 and using "Inherit".

It works with days, but if you have a gap between the days you will get a missing value.
