Hi,

I have a dataset with dates in Stata format. I need to create a
variable with the dates 2 days before the dates I have already.
I mean if I have 01Jan1999 I need to create a variable 30Dec1998, an
so on for all the dates, but haven't been able to write a useful code
for doing that.
Can you help me?

Many thanks!
