June 14, 2026, is the 165th day of the year, with 200 days remaining, and it falls on a Sunday — the second Sunday of June — in the twenty-fourth week of the year.
With 13 national and international days on the calendar, June 14 is anchored by three dates that share the same day for different reasons: the US Army marks its 251st birthday, the American flag was given its official design on June 14, 1777, and World Blood Donor Day honors the birthday of Karl Landsteiner — the man who discovered blood types in 1901 and made modern transfusion medicine possible. A cucumber, a strawberry shortcake, a glass of bourbon, and some feta round out a Sunday that moves between the profound and the pleasant.

National Cucumber Day
Cucumbers — one of the oldest cultivated vegetables, grown for at least 3,000 years — are 96% water, making them both one of the most hydrating foods available and one of the most versatile: eaten raw, pickled, blended into gazpacho, layered on sandwiches, infused into water, sliced over eyes at spas, or turned into raita. National Cucumber Day on June 14 celebrates the quiet overachiever of the vegetable world.
