Could we have a search facility to find caches on their birthdays? i.e. From 5/5/XXXX to 6/6/XXXX to return all caches placed in those 31 days irrespective of years.
This appears to be the one used in the hidden dates grid but I can't find a way of picking specific dates myself.
Using the hidden month tool works to an extent but requires multiple entries as each one is 'year' specific.
