Firdaria come from Persian astrology (Abu Ma'shar) and were used in medieval Europe by Bonatti. Each planet rules a set number of years; each planetary period is split into 7 equal sub-periods in Chaldean order, starting with its own lord. Some authors place the Nodes after Mars for night births. Entertainment only.

Firdaria (from Persian 'fardār') are planetary periods used by Abu Ma'shar and by medieval European astrologers such as Guido Bonatti. Life is divided into a 75-year cycle; each planet and the lunar nodes rule a fixed number of years.
Day births begin with the Sun's 10 years, night births with the Moon's 9. Each planetary period is split into seven equal sub-periods. Enter your birth date and whether you were born by day or night.
