Excel function array formula based on sumif to find minimum count

I have some data where I want to find the minimum number of days it takes to reach a total sum based on some criteria.

Essentially the data is like this:

Date        Season  Recieval
1/01/2006   2006    500
2/01/2006   2006    100
3/01/2006   2006    150
…       
10/12/2009  2009    300

etc

Want I want to do is find a formula that finds the minimum number of days it takes to reach a receivals total for the season.

The formula below is what I have tried so far with no avail.

 =MIN(COUNT(IF(SUMIFS(C:C,B:B,"2006")>2000,DATA!A:A)))

It doesn't matter what point it starts from, but it must take the minimum number of days to reach the 2000.

Output should be a number eg 39 (39 days consecutive to sum up to receivals of 2000).

Essentially what I want to generate is the minimum number of consecutive days required to reach the total of 2000, regardless of the starting point.

Cheers!

If your Dates are in the range A2:A25 and Recieval in C2:C25, then try this...

=INDEX(A2:A25,MATCH(TRUE,INDEX(SUBTOTAL(9,(OFFSET(C$2:C25,,,ROW(INDIRECT("1:25")),1)))>=2000,),0))-A2

The formula will get you the no. of days to reach total 2000 receival in column C.

Or if you just need to count the consecutive dates, please try..

=MATCH(TRUE,INDEX(SUBTOTAL(9,(OFFSET(C$2:C25,,,ROW(INDIRECT("1:25")),1)))>=2000,),0)

Remember both the formulas are Array Formulas which require a special key stroke Ctrl+Shift+Enter instead of Enter alone.
