Find Value Based On MAX Value

[Beaker Rex]

Hello All,
Major noob here, I'm trying to find the cell in Column A that corresponds with a max formula in the B column. if you look at the attachment, you see at B34 the max for B column is "12.43". I need to find the cell in A column that will tell me the "Date" of that max. If the max changes I would like the date to change with it.

Thanks in advance

Mike
