I haven't compiled this, but something like this should work:

greg_year year = v1_Date_date.year();
greg_month month = v1_Data_data.month();
greg_day end_of_month = gregorian_calendar::end_of_month_day(year,month)
date_period dp(date(year, month,1), date(year, month, end_of_month));

Hmm, this function should probably be added to the period class.  In 
the meantime this should work:

date_duration dd = dp.end() - dp.begin();
