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. + + Source: \l {https://en.wikipedia.org/wiki/Islamic_calendar}{Wikipedia page 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. + + \sa QIslamicCivilCalendar, QCalendar +*/ + +bool QHijriCalendar::isLunar() const +{ + return true; +} + +bool QHijriCalendar::isLuniSolar() const +{ + return false; +} + +bool QHijriCalendar::isSolar() const +{ + return false; +} + +int QHijriCalendar::daysInMonth(int month, int year) const +{ + if (year == 0 || month < 1 || month > 12) + return 0; + + if (month == 12 && isLeapYear(year)) + return 30; + + return month % 2 == 0 ? 29 : 30; +} + +int QHijriCalendar::maxDaysInMonth() const +{ + return 30; +} + +int QHijriCalendar::daysInYear(int year) const +{ + return monthsInYear(year) ? isLeapYear(year) ? 355 : 354 : 0; +} + +const QCalendarLocale *QHijriCalendar::localeMonthIndexData() const +{ + return locale_data; +} + +const ushort *QHijriCalendar::localeMonthData() const +{ + return months_data; +} + +QT_END_NAMESPACE |
