MartinLiss, that would work but now I need a function to produce A1,  Jan 1 of the year I select.  Say I have 2015 in a cell and I want A1 to be 1/1/2015

If "2015" is in A2 the put this formula in A1

I see this question has been answered but I'm a little confused - isn't the requirement to get a week number from a date? Martin's solution returns a date, first Wednesday of the year.

btw you can get that more easily with this formula if A1 is 1st Jan date
