st: Summing values within date range
Date

Hello all,
I would like to sum values within a date range in a panel without
using the command rolling (takes a lot of time to run).
To be a bit more specific, I have a continuous 12 year panel and I
would like to sum values over a range of 3 or 4 months for each member
of the panel.
So observation 1 would be a sum of x values for dates t(1) to t(120)
and observation 2 would be a sum of x values for t(2) to t(121) and so
on. The date is is in xx/xx/xxxx format and not indicated as a number.
(Working with Stata10mp)
Thanks in advance,
William
