The following general rule for finding the date of commencement of any Mohammedan year has a maximum error of a day: Multiply 970,224 by the Mohammedan year, point off six decimal places, and add 621.5774. The whole number will be the year a. d., and the decimal multiplied by 365 will give the day of the year.
