fix using correct year for calender week

What does this MR do?

Fixes that the correct year is used from the date. you can not use the %Y (year from the date ) in combination with %v(calender week). There are weeks that break throughout a year. The correct value is %x to use the year from the calender week.

E.g. 01.01.2022 is calender week 52 but in the year 2021

The 27.12.2022 is also week 52 but in the year 2022.

Using the year from the date would result in counting pickups from 01.01.2022 to the KW of the end of the year. Solution : The year of the calender week has to be used and not the year from the actual date.

How confident are you it won't break things if deployed?
