You didn't need to invent a type to do this -- you just added a function to
the date. You would have to reverse it to be what Daryle is suggesting:

 date d(...);
 some_month_type x(2004, Jun);

But we already have date_period for this:
 date start_of_month(...), end_of_month(...);
 date_period dp(start_of_month, end_of_month);

So why not a date_period generator function instead?
  date_period make_month_period(greg_year y, greg_month m);
Then it would be:
  date_period dp = make_month_period(2004, Jun);
  if (dp.contains(d)) // or is_after, is_before, ...

ps: And where I live you can bank on June being hot :-)
