15 | \brief The QRomanCalendar class is a shared base for calendars based on the |
16 | ancient Roman calendar. |
17 | |
18 | Calendars based on the ancient Roman calendar have several common properties: |
19 | they have the same names for months, the month lengths depend in a common |
20 | way on whether the year is a leap year. They differ in how they determine |
21 | which years are leap years. |
