IF and MAX in one formula but two criterias

Column A is listed week 1 to 4 for a month. Column B has the dates for the week. Column C has got various values ranging from 1 to 50.

Now the question. Using Column A as our first criteria, which day in week 1 is the best days performance for the week (remember you have a few 2006/09/04s).

The answer must provide the day and the value.

Anybody who can provide the correct working answer, can go home early.

Assuming the maximum is unique! the values are positive. Extend the ranges as appropriate

Value entered in H6
=MAX(IF(A2:A12=1,C2:C12,0))

Date
=OFFSET(b1,MATCH("1"&h6,A2:A12&C2:C12,0),0)

Both the formulas are arrays and entered with shft ctrl enter
