Yes, it's Flag Day! (A "patriotic observance," but not technically a federal holiday. See 36 U.S.C. sec. 110.)
But check out Gov. Code section 420 to learn about "The Bear Flag [that] is the State Flag of California," because today is also the anniversary of the 1846 "Bear Flag Revolt" -- in which 33 Americans arrested the Mexican general in Sonoma, and declared the "Bear Flag Republic" as an independent nation and raised a flag emblazoned with a bear and a star to symbolize independence from Mexico. The Bear Flag was adopted as California's state flag upon joining the union in 1850.
Appellate lawyers are often interested in typography and design--issues that also relate to flag design. A link to an outstanding TED Talk about vexillology is here, which presents valuable lessons about visual presentations of all sorts.
And speaking of holidays, see Gov. Code section 6719, and prepare something fun for Juneteenth this Saturday: "The Governor shall proclaim the third Saturday in June of each year to be known as “Juneteenth National Freedom Day: A day of observance,” to urge all Californians in celebrating this day to honor and reflect on the significant roles that African-Americans have played in the history of the United States and how African-Americans have enriched society through their steadfast commitment to promoting freedom, brotherhood, and equality."
Back to appellate law: Tomorrow morning the Cal Supremes will issue their opinion in Ryan v. Rosenfeld. What amazingly significant issue of statewide import will be resolved? How about: Is the denial of a motion to
vacate the judgment under Code of Civil Procedure section 663 separately appealable? Yes, we care!
