weeks in a year

Posted on 16th Feb 2014 07:03 pm by admin

hi,

i found this snippet on php.net
QuoteFor the week number for weeks starting on Sunday:

<?php
function week_of_year($month, $day, $year) {

$day_of_year = date('z', mktime(0, 0, 0, $month, $day, $year));

/* Days in the week before Jan 1. If you want weeks to start on Monday make this (x + 6) % 7 */
$days_before_year = date('w', mktime(0, 0, 0, 1, 1, $year));

$days_left_in_week = 7 - date('w', mktime(0, 0, 0, $month, $day, $year));

/* find the number of weeks by adding the days in the week before the start of the year, days up to $day, and the days left in this week, then divide by 7 */
return ($days_before_year + $day_of_year + $days_left_in_week) / 7;

}
?>


so if i go : week_of_year(1, 3, 2010) (sunday)

the week shows as 1, because the script is set to begin new week on sunday,

however i am confused by his instruction " (x + 6) % 7 " to have the week start on a monday

what part of the script do i apply this equation ???

thanks
