Number of days since 1/1/1960.

Ciao, Say I have data on the month (january, february) and year (1951, 1952) that individuals have been born and want to create a SAS formatted date that equals to the number of days since 1/1/1960. How can this be done?

I accidentally made this post after resolving answer. Excuse me.

But the question could still be someone else's question and so the answer remains of interest. If you have numeric months 1 to 12 and years like 1952 then

gen daily_date = mdy(month, 1, year) 

is a Stata daily date, also with origin 1 January 1960, as is

gen daily_date = dofm(ym(year, month)) 

In each case, follow with something like

format daily_date %td
