The Origins of June Dairy Month

In 1937, seasonal milk production reached its annual peak. Spring calving and pasture turnout pushed output beyond what the market could absorb, and the resulting surplus weighed on prices. The strain extends beyond milk prices. June overlaps with heavy spending on inputs for spring planting, so weak milk prices arrive alongside high input costs. The response to the surplus came from chain store grocers.

A group of chain stores established National Milk Month in 1937 to raise milk consumption during the production peak. The campaign ran from June 10 through July 10, and the National Dairy Council supplied promotional materials to the 6,300 stores that participated in the first two years. The original slogan appears in two forms across sources, “Keep Youthful—Drink Milk” and “Stay Youthful—Drink Milk.” The goal was direct: increase demand to move surplus milk.

By 1939, the National Dairy Council narrowed the campaign to the month of June and renamed it June Dairy Month. The new name widened the focus from milk to all dairy products.

The Second World War interrupted the effort. Promotion gave way to wartime supply concerns, and retailers concentrated on keeping dairy products available to customers. After the war, the industry rebuilt the campaign and redirected its purpose toward regaining lost butter sales. In 1947 it adopted the slogan “30 Days for ADA in June,” referring to the American Dairy Association, with the goal of “sales, not surplus.” By 1950 retailers, producers, and processors promoted June Dairy Month jointly.

In 1955 the American Dairy Association assumed national leadership of the campaign and added advertising and merchandising to the promotional program. A grocer-led tool for moving surplus milk had become a coordinated industry enterprise.

June Dairy Month has broadened well beyond its original purpose. It recognizes dairy farmers, promotes dairy products, and informs consumers about dairy nutrition. The seasonal economics that created it persist. Production still peaks in late spring, the spring flush still pushes supply against demand, and farm expenses still run high through planting. What began as a grocer campaign to move surplus milk endures as a fixture of the dairy calendar.
