National Pumpkin Pie Day takes place on Christmas Day, the 25th of December 2018. Pumpkin pies are very popular in the USA and therefore it is no wonder that there is a National Pumpkin Pie Day, although the creator of this sweet food holiday is unknown. The pumpkin harvest is in autumn but there is no relation to the Christmas date documented. However pumpkin pie is a delicious and classic dessert. It is often served with cinnamon, cream or nuts. Of course enjoying a fine piece of pumpkin pie is highly recommended on National Pumpkin Pie Day. Pumpkin pie is also commonly served at Thanksgiving.
