How to: Show the date when the max value happened?

[LRATOZ]

Hi,
To keep things simple:
Column A (Date)has the dates
Column B (Value) has the values

I want to find the MAX-value AND the date it happened in pivot tables
Now when I run pivot tables it shows me the year and the quarters.
I don't need the Quarters, so when I deselect this then it shows me the months and the maximum value for that month.
This is a step in the right direction.
I now see the following:
Year, month, max value
My problem is that I would like to see the following:
Year, month, max value and the date it occurred. (Similar to the INDEX function).

Can somebody steer me in the right direction please?
Many thanks in advance!
By the way: I am new to pivot tables, please be gentle

OK, to make it easier I have copied part of my pivot table:

As you can see I added a column outside the pivot table and used the INDEX function to show the date when the max temperature happened.
Can this be done inside the pivot table itself?
I have tried to insert the 4th column between the 2nd and the 3rd column but the pivot table doesn't allow that to happen.
Hopefully this might be a bit clearer compared to the previous message.
Cheers,
Luke
