Administrative Professionals Day honors the office professionals — assistants, coordinators, and executive support staff — whose organizational work keeps institutions running, observed on the Wednesday of the last full week of April. Battle of San Jacinto marks April 21, 1836, when Sam Houston’s Texan forces routed Santa Anna’s Mexican army in 18 minutes, securing Texas independence. Festival of Ridvan is the most sacred Baha’i holiday, commemorating Baha’u’llah’s twelve-day declaration in the Garden of Ridvan in Baghdad in 1863. Wrinkles, a desk calendar, an 18-minute battle, and a garden declaration.
