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)
