Civil procedural rules distinguish sharply between raw elapsed calendar days and true judicial business days. While calendar day counting marches continuously through Saturdays, Sundays, and legal closures, court day counting pauses whenever the courtroom doors and clerk filing desks are closed. The Court Calendar Calculator enables legal teams to audit any date span or project forward across a defined quantity of open court sessions:
- Select Calculation Mode: Choose "Date Range Audit" to decompose an existing calendar window into open court days, weekend closures, and holiday shutdowns; or toggle to "Add Court Days" to determine the exact terminal court date resulting from adding N judicial days to a start date.
- Specify the Sovereign Judicial System: Switch between California State Courts (governed by California Government Code § 6700 and California Code of Civil Procedure § 135) and Federal District Courts (governed by Title 5 of the United States Code § 6103).
- Designate Target Calendar Dates: Enter the starting reference date (Day 0) and terminal target date. Day 0 is excluded from the business day computation pursuant to standard procedural canons.
- Examine the Closure Inventory & Status Indicator: Inspect the four primary metric tiles and review the itemized list of official court holiday closures occurring within your audit window.
Under California Government Code § 6700 and California Code of Civil Procedure § 135, every full day that is designated a judicial holiday represents an official closure of all county superior courts and appellate district divisions. If a statutory filing deadline or motion hearing notice falls on such a closure, California Code of Civil Procedure § 12a mandates that the period is extended to and including the next day that is not a holiday.
For federal district courts operating under Title 5 of the United States Code § 6103 and Federal Rule of Civil Procedure 6(a)(6), the legal holiday schedule includes federal statutory holidays and any day declared a holiday by the President or Congress. Whenever a federal filing deadline falls on a legal holiday, Rule 6(a)(1)(C) automatically continues the deadline to the end of the next day that is not a Saturday, Sunday, or legal holiday.

Critical Engineering Tolerances & Operational Standards
Judicial court calendars are strictly regulated by statutory codification. Filing desks operate on precise business day thresholds where electronic filing timestamps must reflect court open days.

Operating Guidelines, Quality Adherence & Error Prevention
Never assume that federal and state courts share the same closure calendar. Columbus Day is open in California state courts but closed in federal court; the Day After Thanksgiving is closed in California state courts but open in federal court.
- Columbus Day is an open judicial day in CA State Courts
- Day After Thanksgiving is a CA judicial closure (Gov. C. § 6700)
- Always cross-check specific jurisdiction holiday rules
Under California CCP § 1010.6(a)(3) and CRC Rule 2.251, documents electronically filed by 11:59:59 PM on a court day are deemed filed on that court day. Documents filed after midnight or on weekends roll to the next court day.
- 11:59:59 PM is California statewide electronic cutoff
- Weekend filings deemed filed on Monday morning
- Federal CM/ECF cutoffs vary by local district rules
When an annual holiday falls on a Sunday, courts observe the closure on Monday. If an annual holiday falls on a Saturday, California state courts observe the holiday on the preceding Friday under CRC Rule 1.11.
- Sunday holidays shift forward to Monday
- Saturday holidays shift backward to Friday (CRC 1.11)
- Observed holiday dates are non-judicial days
Under California Government Code § 68115, individual superior courts may implement emergency administrative closures during disasters or emergencies. The closed days are deemed statutory holidays under CCP § 12b.
- Emergency closures authorized under Gov. Code § 68115
- Deemed legal holidays under CCP § 12b
- Filing deadlines automatically extended to next open day

Yes. Under California Code of Civil Procedure § 12b and Government Code § 68115, if the courthouse clerk's office is closed for filing due to a natural disaster, public emergency, or administrative order, that day is deemed a holiday for purposes of computing civil filing deadlines under CCP § 12 and § 12a.
