December 15 Holidays

Bill of Rights Day marks December 15, 1791, when Virginia became the 10th of 14 states to ratify the first ten amendments to the U.S. Constitution — giving Americans the freedoms of speech, religion, the press, assembly, and petition, as well as rights against unreasonable search and seizure. International Tea Day is a second annual observance on December 15 — distinct from the UN’s May 21 observance — celebrating tea as the world’s most popular beverage after water, with 3.7 billion cups consumed daily across more than 160 countries. National Cupcake Day celebrates the miniature cake format first documented by Hannah Cooley in 1796 — a format that Magnolia Bakery popularized in New York in the early 2000s and that generated a nationwide boutique cupcake industry. Cat Herders Day was created to celebrate the experience of managing people or projects that resist coordination — and to honor the project managers, teachers, and herding dogs who attempt it.
