Betreff: st: Categorising dates

Dear Statalisters

I have a list of daily dates inthe format, for example, 23 Sep 09, and
need to create two variables. One is to categorise the days into
weekly data (so week commencing on a Monday). The second is to create
a variable cataegorsing the daily data into monthly data.

I would be grateful for advice on how to do this.

Many thanks.
