Cal. Education Code § 44988

Prior to July 1 of any school year, the governing board of any school district may designate other days during such year as the holidays to which certificated employees are entitled in lieu of the holidays on February 12 known as “Lincoln Day,” the third Monday in February known as “Washington Day,” the last Monday in May known as “Memorial Day,” or November 11 known as “Veterans Day,” provided that such designated days will provide for at least a three-day weekend. Certificated employees shall be required to work on the regular holiday for which another day is designated pursuant to this section, and for work of eight hours or less, shall be paid compensation at their regular rate of pay. If any certificated employee would be entitled to the regular paid holiday but would not be in a paid status during any portion of the working day immediately preceding or succeeding the day so designated in lieu of such holiday and therefore would not be entitled to such day in lieu of the holiday, he or she shall be entitled to the regular holiday. This section shall not be construed to authorize the maintenance of schools on holidays other than as provided in Article 3 (commencing with Section 37220) of Chapter 2 of Part 22.
