How the math works
Step 1 — 30 days. Responses to interrogatories (CCP § 2030.260), requests for production (CCP § 2031.260), and requests for admission (CCP § 2033.250) are due 30 days after service. The clock runs from the date on the proof of service.
Step 2 — service extensions. How the discovery was served changes the real due date:
| Method of service | Extension | Authority |
|---|---|---|
| Electronic service | +2 court days | CCP § 1010.6 |
| Personal service | none | CCP § 1011 |
| Mail — within California | +5 calendar days | CCP § 1013 |
| Mail — outside California, within U.S. | +10 calendar days | CCP § 1013 |
| Mail — outside U.S. | +20 calendar days | CCP § 1013 |
| Express mail / overnight delivery | +2 court days | CCP § 1013 |
| Mail — Safe at Home confidential address (address-confidentiality program) | +12 calendar days | CCP § 1013 |
Step 3 — the roll. If the final day lands on a weekend or judicial holiday, the deadline rolls forward to the next court day (CCP § 12a). California courts close for holidays most calendars miss — including Lincoln’s Birthday (February 12) and Native American Day (fourth Friday of September). This calculator validates against the official Judicial Council holiday calendar.
