Details

The WEEKUw. format writes a week-number format. The WEEKUw. format writes the various formats depending on the specified width. Algorithm U calculates the SAS date value by using the number of the week within the year (Sunday is considered the first day of the week). The number-of-the-week value is represented as a decimal number in the range 0–53, with a leading zero and maximum value of 53. For example, the fifth week of the year would be represented as 05.

Refer to the following table for widths, formats, and examples:

If the first Monday of January is the 2nd, 3rd, or 4th, the preceding days are part of the last week of the preceding year. The WEEKWw. format writes the week number of the year as a decimal number in the range 00–53, with Monday as the first day of week 1. The WEEKUw. format writes the week number of the year (Sunday as the first day of the week) as a decimal number in the range 0–53, with a leading zero.
