Let us find the anno domini which coincides with the beginning of the hegira lunar year 1404; 1403 x 0,97023 = 1361.23 would become the hegira solar year which starts on the 16th of July. Then 1361.23 + 621.54 = 1982.77 would be (0.24 x 30 = 7.2) the eighth day of (0.77x12=9.24) the tenth month of the year 1983 A.D.
