| \brief The QHijriCalendar class supports Islamic (Hijri) calendar implementations. |
| |
| \section1 Islamic Calendar System |
| |
| The Islamic, Muslim, or Hijri calendar is a lunar calendar consisting of 12 |
| months in a year of 354 or 355 days. It is used (often alongside the |
| Gregorian calendar) to date events in many Muslim countries. It is also used |
| by Muslims to determine the proper days of Islamic holidays and rituals, |
| such as the annual period of fasting and the proper time for the pilgrimage |
| to Mecca. |
| |

| on Hijri Calendar} |
| |
| \section1 Support for variants |
| |
| This base class provides the common details shared by all variants on the |
| Islamic calendar. Each year comprises 12 months of 29 or 30 days each; most |
| years have as many of 29 as of 30, but leap years extend one 29-day month to |
| 30 days. In tabular versions of the calendar (where mathematical rules are |
| used to determine the details), odd-numbered months have 30 days, as does |
| the last (twelfth) month of a leap year; all other months have 29 |
| days. Other versions are based on actual astronomical observations of the |
| moon's phase at sunset, which vary from place to place. |
