December 29 National Days

December 29, 2025, is the 363rd day of the year, with two days remaining until the end of the year. As the calendar nears its close, the day’s observances highlight finishing unfinished tasks, celebrating the cello, and recognizing the historic regional dish known as pepper pot.

Below is a list of all three national and international days observed on December 29, each explained briefly.

National & International Days on December 29

International Cello Day honors the cello and the musicians who bring its sound to life. Established in 2015 by a global group of cellists, the date marks the birthday of Pablo Casals (1876), whose work transformed the instrument’s role in classical music. Casals is especially remembered for reviving Bach’s Cello Suites and helping establish the cello as a respected solo instrument rather than a purely supporting one.

National Pepper Pot Day recognizes Philadelphia Pepper Pot, a highly seasoned stew traditionally made with tripe and vegetables. Often called “the soup that won the war,” it is linked by legend to Valley Forge, though its true roots trace to West African and Caribbean cooking traditions that shaped early Philadelphia cuisine.

Tick Tock Day, also known as Still Need To Do Day, encourages finishing lingering tasks before the year ends. With only a few days left on the calendar, the observance focuses on clearing unfinished projects from the past year and tying up loose ends before the new year begins.
