If you are doing this, even better would be to include the following in profile.do

global today date("\`c(current_date)'","DMY")

Note the backslash before the open-single-quote (`), which means the global macro contains the literal string `c(current_date)' which is evaluated every time the global is called, rather than containing the value of c(current_date) at the time you assign the global.

Then $today will give you the date number, and it will work even if you've been running Stata since yesterday.

You can see what's "really" in $today with -macro list-:

. mac list today
today: date("`c(current_date)'","DMY")

. di $today
17751

. di %d $today
07aug2008

Jeph,

If you frequently need today's date formatted as a Stata date value or some other specific format like the one below, you might find it convenient to make a global macro like $today in your profile.do file.

The risk would be that if you leave your computer (and Stata) on overnight, the macro would refer to an earlier date.

Even if one isn't using it to compare with a date
variable, one usually wants to reformat before using,
and converting to a date value is the easiest way
to proceed, eg,

local today=string(date("`c(current_date)'","DMY"),"%tdCCYY.NN.DD")
