Tājika Varṣaphala
Varṣaphala annual chart
The Tājika year is measured from one solar return to the next — the moment the Sun regains the exact longitude it held at your birth. This calculates that instant, casts the annual figure for your birthplace, and reports the Muntha, the lord of the year, all twenty-one configurations, the seventy-five Sahams and the Pātyāṃśa periods.
Where the classical sources leave a question open, this reading says so rather than choosing for you. Those disclosures appear beside the values they affect.
The annual chart runs from one solar return to the next, so this names a birthday year rather than a calendar year. The year you were born is the first revolution.
