c11.1

The initial point of the Seleukidan era has been fixed by Fynes Clinton to the 1st of October 312 B.C., in the beginning of Olympiad XVII, 1.* According to Ulugh Beg this era began 12 years after the death of Alexander, and 340,700 days before the Hijra of Muhammad, 16th July A.D. 622. Now 311 complete years B.C. plus 621 complete years A.D. = 932 Julian years, contain 340,414 days, which deducted from 340,700 leave 286 days to be accounted for. As the Hijra era dates from 16th July there are 196 days in A.D. 622, which leave only 90 days prior to the beginning of B.C. 311; so that, according to Ulugh Beg, the Seleukidan era must have begun on the 3rd of October B.C. 312. The other datum of 12 years after the death of Alexander does not refer to the actual date of Alexander's death, but to the initial day of the 425th year of Nabonasar, 12th November 324 B.C., in which year Alexander died. Twelve years later places the beginning of the Seleukidan era near the end of the year 312 B.C.
