There is no rhyme or reason to the majority of food holidays out there. Most are announced a holiday by the marketing team of a brand, or declared by the popular food day website Foodimentary. There are days that do have a history behind them like National Doughnut Day, which takes place on the first Friday of June. Women volunteering for the Salvation Army would bring doughnuts to the soldiers during World War I to raise their spirits. The day was created by the Salvation Army as a way to raise funds and awareness for the volunteers.
I was delighted to find out that there is a random, fun and quirky food holiday for every day of June. On top of that, they are mostly desserts and we aren't complaining.
