The Date function have a day of the week parameter 'w'
This parameter should return 7 for sundays, not 0 to be ISO 8601
compilant
Why
http://se.php.net/date :
> w Numeric representation of the day of the week
> 0 (for Sunday) through 6 (for Saturday)
This week parameter do not return leading zeros when used like
Date('o\WWw'), Date('o\-\WW\-w')

- day of the week is represented by one decimal digit. Monday shall be
identified as day [1] of any calendar
week, and subsequent days of the same week shall be numbered in ascending
sequence to Sunday (day [7]).) like:
