M code for a DAX expression

[mtrevisiol]

Hi everyone,

I need to transform this DAX expression in M:

Week= YEAR(Calendar[Date]+26-WEEKNUM(Calendar[Date],21)) & "-" & IF(WEEKNUM(Calendar[Date],21)>=10, WEEKNUM(Calendar[Date],21), "0" & WEEKNUM(Calendar[Date],21))

which calculates the week of the year followed by the year for each date of my calendar, according to the European system:

Can you help me? Many thanks!
