Last year when the Governor signed the bill that created Native American Day (a holiday on the 4th Friday in September) it was mistakenly deemed as a court holiday, which was not the intent, please note the following:
SB 85 was signed by the governor on 6/24/2015.
“SEC. 2. Section 135 of the Code of Civil Procedure is amended to read:
135. Every full day designated as a holiday by Section 6700 of the Government Code, including that Thursday of November declared by the President to be Thanksgiving Day, is a judicial holiday, except September 9, known as “Admission Day,” the fourth Friday in September, known as “Native American Day,” and any other day appointed by the President, but not by the Governor, for a public fast, thanksgiving, or holiday. If a judicial holiday falls on a Saturday or a Sunday, the Judicial Council may designate an alternative day for observance of the holiday. Every Saturday and the day after Thanksgiving Day is a judicial holiday. Officers and employees of the courts shall observe only the judicial holidays established pursuant to this section
