📘 About the Firdaria
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.
✏️ Worked example
Born 15 June 1990, day birth
You get| Current firdar (main time lord) | ☽ Moon — ages 31 to 40 |
| Sub-period lord | ☉ Sun (Thu, 6 Aug 2026 – Fri, 19 Nov 2027) |
| Sequence | Day birth — starts with the Sun; the full cycle is 75 years |
| Age now | 36.3 years |
☽ Moon — ages 31 to 40; ☉ Sun (Thu, 6 Aug 2026 – Fri, 19 Nov 2027).
