I'm converting a set of dates to the end of the respective month, for
instance:
20Jan91 -> 31Jan91
10Mar05 -> 30Mar05
Etc.
Does anyone knows a function in Stata that does this automatically?
---------------------------------------------
How about this:
// Create 3 dates for the exercise:
clear
input d m y
20 1 1991
10 3 2005
24 12 2005
end
gen date=mdy(m,d,y)
drop m d y
format date %d
// Here we go:
gen dd = day(date)
gen mm = month(date)
gen yyyy = year(date)
gen mm1=mm+1 if mm<12
replace mm1=1 if mm==12
replace yyyy=yyyy+1 if mm==12
gen date1 = mdy(mm1,1,yyyy)-1
format date1 %d
list
I just subtracted 1 from the first day in the following month.
But note the small "complication" with December.
Hope this helps
Svend
