I have an array for just the dates, I actually zipped together my @dates array and my @tifs array to create the %hash. So if it would be easier doing the math in the array, that's fine, since I have the elements in the hash, I can always reference the hash later to get the tif corresponding to the date.

So, would I just use each to iterate through my date array to do the necessary comparisons?
