The first lesson is to use the on-line help, but after -search- if you
don't know
what entries to look up. So
. search double
points to help on -data types-.
gen var1n = date("15/" + var1, "DMY")
var2 sounds as if it is already as you want it. It is already numeric.
For subtraction, use -
e.g. gen var3 = var2 - var1n
P.S. the spelling is "Stata"!

STATA Dndee
I am new to STATA
I have 2 variables and want to set them as date with
as in the following:
1-Var1- Storage type str8, display format 0.9s. It has
month and year only like: 06/2005 . I want to assign
the day for it then set the day at 15 of each month :
15/05/2005.
2- Var2- Storage type double, display format %td and
writen like 26Nov2005. I want this to set it as date
and actualy don't know what double means.
3- Then I have to change them to numeric (var1n,
var2n) and substracte them: var3=var2n-var1n.
