| Calendar (double jd) | |
| virtual double | getJD () const |
| Get Julian day number from a calendar date. | |
| virtual QVector< int > | getDate () const |

| Protected Attributes inherited from Calendar | |
| double | JD |
| QVector< int > | parts |
| date expressed as JD(UT), including day fraction (ready to interact with the main application) | |
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.

dayNumber[1..13]-nameIndex[1..20] We face a problem as the date is not unique. We can only find the date before current JD which matches the parts.
