Work week Formula help

Do anyone know a formula to calculate the "work week" from a start date.

So see attached image. I can calculate what week in the year it is. but I need the yellow column to reflect the work week from the start date (the first green date in this case tuesday 4-4) The colors in green are imported from another sheet.

So I have numbers in the helper column that I would like it to report. week 1, 2, 3 ect.

Start date could be any workday.

    Generally, if your dates are within the same calendar year: =WEEKNUMBER(Date@row)-WEEKNUMBER($Date$1)

    If not, there'd be a slightly complicated additive to the formula that would account for the shift... may require a helper column.
