August 1 Holidays

National Girlfriend Day was created to celebrate the girlfriends — platonic and romantic — whose emotional support, laughter, and loyalty form the backbone of many social lives. Colorado Day marks August 1, 1876, when Colorado was admitted as the 38th U.S. state — nicknamed the “Centennial State” because its admission coincided with the 100th anniversary of American independence. Emancipation Day (Guyana) marks August 1, 1834, when the Slavery Abolition Act formally ended slavery in the British Empire — observed in Guyana and other Caribbean nations as the most significant date in their post-colonial history. National Mustard Day is observed on the first Saturday of August, celebrating the condiment ground from Brassica seeds into a $400 million annual U.S. market — from French’s yellow to Dijon’s Chardonnay-spiked stone-ground.
