It's not calculated. The First Seder is always in the evening next to the 14th
of Nisan. As for the number of months (12 or 13) and length of some of them (29
or 30), we get 6 combinations and therefore 6 lengths of the year, from 352 to
384 days. The extra month occurs 7 times in a 19-year cycle. The extra days are
added so that Yom Kippur (Day of Atonement) could not fall on Friday or
Sunday -- it's too difficult to keep sabbath restrictions two days in line :)
