  * Returns a MySQL expression for selecting the week number based on the start_of_week option.
+ * @ticket 52220 - Former used MySQL::WEEK modes 0 and 1 changed to 2 and 3 respectively.
+ * Modes 0 and 1 return weeks numbers from 0 to 53, while modes 2 and 3 return week numbers from 1 to 53 which is corresponds to our documentation:

+ * Also, WP ignores GET parameter w=0 and didn't allow to select posts from the first week (w=0) of the year correctly with 0 and 1 used modes.
+ * Modes 2 and 3 fix this issue and allow to select posts from the first week of the year correctly.

  * @ignore
