virtual void retranslate ()
 Translate e.g. stringlists of part names.
 
virtual void setJD (double JD)
 Set a calendar date from the Julian day number Subclasses set JD and compute the parts and possibly other data This triggers the partsChanged() signal.
 
virtual double getJD () const
 Get Julian day number from a calendar date.
 
virtual void setDate (QVector< int > parts)
 set date from a vector of calendar date elements sorted from the largest to the smallest. More...

Detailed Description

The implementation follows CC. The "name" is not a month but also changes every day. The traditional writing is number-name, which is also used in the parts.
