/** WEEK(date)
WEEK ( date , first )
With a single argument , returns the week for date , in the range 0 to 53 ( yes , there may be the beginnings of a week 53 ) , for locations where Sunday is the first day of the week . The two - argument form of WEEK ( ) allows you to specify whether the week starts on Sunday or Monday and whether the return value should be in the range 0 - 53 or 1 - 52 . Here is a table for how the second argument works :
Value Meaning
0 Week starts on Sunday and return value is in range 0 - 53
1 Week starts on Monday and return value is in range 0 - 53
2 Week starts on Sunday and return value is in range 1 - 53
3 Week starts on Monday and return value is in range 1 - 53 ( ISO 8601 )
