One possibility is to read the documentation.
-help dates and times- is a place to start. It is long but a few
seconds after using operating system search within the window you
would find reference to -quarterly()-.
Consider
. gen qdate = quarterly("2001q1", "YQ")
. l
+-------+
| qdate |
|-------|
1. | 164 |
+-------+
. format qdate %tq
. l
+--------+
| qdate |
|--------|
1. | 2001q1 |
+--------+
In your case that might be
gen qdate = quarterly(Quarter, "YM")
format qdate %tq
See also help for -tsset-.
