Afghan Months

Dari months, in a solar Hijri calendar. The first six months have 31 days, the next five 30 days and the last 29 days, or 30 in a leap year, determined by counting the number of days between two vernal equinoxes. Much more accurate than the Gregorian calendar which deviates from the solar year by one day every 3236 years: Hamal, Sawr, Jawza, Saratan, Asad, Sonbola, Mizan, Aqrab, Qaws, Jadi, Dalva, Hut.
