The Least Photographed Day
Updated:
Over the past 15 years I've only taken a total of 14 photos on February 10: It's the "least photographed day".
This statistical nugget comes from a feature of the photo organizing software I use where you can sort photos by month and day for an instant "throwback Thursday" experience. (It's up to 88 now; and February 16 is at the bottom with 20 photos.)
