613 | * The week number and year number of a date may actually be different | ||

615 | * example if Jan 1 year falls on a Friday, the week number will | ||
616 | * be the last week number for the previous year (52 of year - 1). Another | ||
617 | * example is that the date 2001-12-31 falls on a Monday, its week number | ||
618 | * is 1 and its year is 2002. This function provides stripped down | ||
619 | * version of the alogrithm described in | ||
