Weeks of Year

Hello, everyone,

I need some help.
So:

1st - at the moment, I have a column from number 1 to number 52 (for example, weeks of the year 2023).
2nd - I have a planning project that starts at week 45 and I need 10 weeks to complete it.

- 45 (week) + 10 (plan time) ≠ 55 (week - doesn't exist)
- 45 (week) + 10 (plan time) ≠ 2 (2nd week of 2024 - I have Christmas vacation in a week)
- 45 (week) + 10 (planned time) = 3 (3rd week of 2024)

3rd - I need to know if I can do this in Excel. Put week 51 at the end of the year with a limit and go to week 1 to show a real result and not to week "55".

Thank you for your attention
