The World Pie Day observed on the 14th of March every year, is an annual celebration of the mathematical number Pi. In many places the entire month of March is observed as the 'Pi Month'. Although nothing to do with food, the most common way to celebrate the occasion is by having lots and lots of pie.
The day is also the birthday of Albert Einstein, hence at places people apart from eating pies also remember the famous scientist in numerous ways. Some of the unique ways of celebrating Pie Day are throwing pies at each other, organizing pie eating contests, eating and sharing slices of pie and distributing Pies made at home among people.
