I found this useful for working out the week of the year if you want to for example find the third
Tuesday of the year, using the date("w") function could return 3 or 4 for the correct day.
This function does not seem to count week one as the first 7 days of the year, but instead the first
4-7 days of the year, dependent on the start day of the year.
Using <?php
$weekofyear = (date("z", $stamp) - (date("z", $stamp)%7))/7 + 1;
?>
seems to return the week number by counting each week through the day number of the year and
counting 7 per week so week 1 is days 1-7, week 2 is days 8-14 etc.
Subtracting the remainder (date("z", $stamp)%7) tidies up the output by ensuring no
decimals remain.
