See [U] 24 for a brief introduction and -help dates and times- for
fuller detail.
If your variables are all numeric then
gen dailydate = mdy(injmo, injday. injyr)
will produce a daily date variable. Then
format dailydate %td
or
formal dailydate %d
will assign a default format for daily dates. You can tune that format
using recipes given in the -help-.
Note that (a) having a values in a variable that Stata will interpret
as dates as you want and (b) assigning a format that displays a date
variable as a recognisable date are quite separate in principle, as
shown by the separate commands above.
