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 AD, and the decimal
multiplied by 365 will give the day of the year.
