Add Lunar Calendar to Windows Mobile 5
A lunar calendar is a calendar whose date indicates the moon phase. This is normally done by having a month which corresponds to a lunation so that the day of month indicates the moon phase. If a calendar tracks the seasons, it is also a lunisolar calendar.
For some lunar calendars, such as the Chinese calendar, the first day of the month is determined by determining the day during which the moment of new moon arrives, according to a particular time zone. Many other lunar calendars are based on first sighting of the lunar crescent. Thus, different lunar calendars differ in which day is considered the first day of the month.
The length of a month orbit/cycle is difficult to predict and varies from its average value. Because observations are subject to uncertainty and weather conditions, and astronomical methods are highly complex, there have been attempts to create fixed arithmetical rules.
The average length of the synodic month is 29.530589 days. This means the length of a month is alternately 29 and 30 days (termed respectively hollow and full). The distribution of hollow and full months can be determined using continued fractions, and examining successive approximations for the length of the month in terms of fractions of a day. In the list below, after the number of days listed in the numerator, an integer number of months as listed in the denominator have been completed
Ok, you have learned enough?
PocketNow just showed how to turn on the Lunar calendar in your WM5.
Look for this registry Key:
HKLM\Software\Microsoft\Calendar\ add the following DWORD value:
ShowLunarCalendar And make it = 1 (DWORD decimal). To disable, just make this value equal to 0.
