First data of a week number

[DoraS]

Hi

I have a date and with that date I know the week of the year, but now I need to know for a week what is the first data of that week.

Ex:  02 March 2022 belongs to week 09/22 but I want a function to returns me the first day of the week 09/22, in that case is 28 February.

Thanks

Dora
