National Walnut Day

National Walnut Day is a holiday that falls on May 17th every year. Although this nut isn’t one of the more popular nuts enjoyed these days, it is one that has been around for a long time. In fact, it’s one of the nuts that has been harvested the longest—with humans harvesting them for about 10,000 years now. It’s no wonder that they have earned themselves a special holiday, a holiday that we think everyone will enjoy once they begin to celebrate it.

The History Of National Walnut Day

Even though you would think that National Walnut Day was a recently invented holiday, the truth of the matter is that it has been around for over 72 years. It was invented in June of 1949 by the Walnut Marketing Board to promote walnuts to the general public. It remained a marketing holiday for a few years, and then U.S. Senator William Knowland introduced a Senate Resolution to declare this day a national holiday. This resulted in U.S. President Dwight Eisenhower declaring May 17, 1958, as National Walnut Day. It has been celebrated on that day ever since.
