Hi, thank you for your project. I allowed myself to add my routine - according to ISO it uses Monday as 1st day of week, anyway.

There you can select your routine as “Horst” and my - as “Pawel”. Please, kindly recognize how it shows days 1 or 2 of January 2020. It is 53rd week vs 1st.

If 1st day of January is Thursday or earlier - then the whole week is 1st week, not the 53rd or 52nd.
