Hi all,

I am using stata 15.1

a general thing: I have realized that when I use the following command to create a difference between two dates of months I get wrong results:

gen FU_mt=(DatumLetzterBesuchimRDI-OPDate)/12

I do get the right days when calculating date difference in days:

gen FU_d=(DatumLetzterBesuchimRDI-OPDate)

For example (12sep2016-12aug2016)/12 gives me 2.583 months
12sep2016-12aug2016 correctly gives me 31 days

I have checked stata forum and google and I dont get to the solution. What am I doing wrong?
