 I propose a correction of the function validate_date_values ($date_query =
 array()) of the /wp-includes/date.php file
 the following 359 to 361 lines:

 {{{
 $date = new DateTime();
 $date-> setISODate ($date_query year?, 53);
 $week_count = $date-> format ('W') = '53'? 53: 52;
 }}}


 may be replaced by a single line (without using the class dateTime):

 {{{
 $week_count = date ('W', mktime (0,0,0,12,28,$date_query year?));
 }}}

 This speeds up the execution of about 1/100 sec because it greatly
 simplifies the calculations.


 Indeed, the number of weeks in a given year is equal to the corresponding
 week number of 28 December.
