How did you calculate the week (with SQL).
There are 2 different functions: WEEK and WEEK_ISO.
When executing WEEK, January first is always in the first week of the year.
According to the ISO guidelines the week numbering is defined as follows:
1. Week always starts with Monday
2. In the first week of a year, the majority of the days must be from the
first year. What is for sure is January, 4th is always in week 1 or the
first Thursday of a year is always in week 1.
That means December 31 can be in the first week of the new year, while
January 3rd can be in the last week of the previous year.
The scalar function WEEK_ISO calculates the week according the ISO
guidelines.
