National Smoothie Day
Celebrated on 06/21/2026
Quick Fact
National Smoothie Day is celebrated on June 21, the longest day of the year, making it the perfect time to enjoy a refreshing blended drink. The word 'smoothie' first appeared in print in the 1920s, but the modern smoothie boom began in the 1960s with the invention of the electric blender.
Origins and Establishment of National Smoothie Day
National Smoothie Day was established in the early 2000s by the National Day Calendar, a private organization that registers and promotes various unofficial holidays. The exact year of its inception is unclear, but it was likely created to capitalize on the growing popularity of smoothies as a health food. The day was intentionally placed on June 21, the summer solstice, to encourage people to enjoy a cold, nutritious beverage at the start of summer.
Evolution and Modern Commemoration
Originally promoted by smoothie chains and health food advocates, National Smoothie Day has evolved into a widely recognized celebration. Retailers often offer discounts or free samples, and social media campaigns encourage users to share their favorite smoothie recipes. In recent years, the day has also been used to highlight the nutritional benefits of smoothies, with many fitness and wellness influencers promoting green smoothies and protein-packed blends.
