Nine Parts

The Nine Parts is a persian medieval time lord technique derived from the Vedic tradition. It was described by Abu Mashar in the "On the Revolutions of the Years of Nativities".

In order to calculate the Nine parts go to the Forecast/Time Lords/Nine Parts... menu and select the following parameters:

• Type. Type of the time conversion:
• Ascensional Time
• Degrees
• Method:
• Abu Ma'ashar - this is the way Abu Ma'ashar describes the method. It requires reversing sub-lords of the first 9th part if the starting point is not the first sub-lord.
• Don't reverse sub-lords. This method uses the regular linear profection of the sub-lord rulers.
• Year. This is the year length (based on various Hellenistic, Medieval and modern sources):
• Tropical Year (default)
• Bija-corrected
• Sidereal year
• Egyptian/Hellenistic (360 days)
• Abu Ma'ashar - year duration is based on Abu Ma'ashar's mundane works
• Masha'allah - year duration used by Masha'allah

The Nine Parts table contains the list of dates when each period and sub-period starts and the ruling planet of that period and sub-period.
