When is National Watermelon Day 2024?
There’s nothing like beating the heat with summertime’s most refreshing fruit, celebrated on National Watermelon Day on August 3.
History of National Watermelon Day
The juicy, refreshing watermelon deserves its own day, that’s why we celebrate National Watermelon Day. Cultivation of this fruit dates back to 2000 B.C., with the first watermelon harvest on record occurring approximately 5,000 years ago in Egypt. Traces of watermelon and its seeds have been discovered on sites of the 12th Egyptian Dynasty, including in the tomb of King Tutankhamen. Paintings of different types of watermelon have also been found in ancient Egyptian inscriptions.
The sweet fruit we enjoy today is the result of mutations over the course of a thousand years of cultivation. Watermelon seeds were sold to traders passing through the trade routes in the Kalahari Desert in Africa. From there, the cultivation of the watermelon spread across Africa. The origin of the progenitor of the watermelon was in Africa, after which it spread into Mediterranean countries and other parts of Europe. By the end of the ninth century, watermelon cultivation became common in China and the rest of Asia.
According to “The Dictionary of American Food and Drink” by John Mariani, the word ‘watermelon’ first appeared in the English dictionary in 1615. The watermelon is commonly known as a type of melon, but it is not in the genus Cucumis. The outer rind of a watermelon is dark green with yellow stripes or spots. Over 300 varieties of watermelon are available in the U.S., ranging from red to white, and come in different shapes and sizes.
