Which date starts the 30-day period?
The period runs from the service of the selected discovery request. The default calculation uses service of the interrogatories; other branches use their own trigger.
Count forward from service. Confirm the event on the docket or in the service record before entering a date.
Read Rule 33The responding party must serve its answers and any objections within 30 days after being served with the interrogatories. A shorter or longer time may be stipulated to under Rule 29 or be ordered by the court.
FRCP 33(b)(2)
This period runs from service as the rule defines it. Do not substitute the filing date, the day a courtesy copy arrived or the day you first read the paper.
Which date do I enter?How are the 30 calendar days counted?
- Exclude the day of the trigger event.
- Count every following day, including intermediate Saturdays, Sundays and legal holidays.
- If the last day is a Saturday, Sunday or legal holiday, continue to the next day that is not one of those.
Exclude the service day and apply FRCP 6(a).
FRCP 6(d) can add three days for specified non-electronic service methods, but not electronic service.
Rule 6(a) also treats a day on which the clerk’s office is inaccessible as excluded from the last day, and sets the filing cutoff at midnight in the court’s time zone for electronic filing. The national calculation does not confirm those local facts.
Read FRCP 6(a)The calculation gives the ordinary national-rule date. Check relevant holidays, the court’s accessibility and its filing cutoff separately.

Fictitious example
Assume the service of the selected discovery request on Tuesday, September 1, 2026 (electronic service of interrogatories), with no order, motion, extension or local closure affecting the result. Electronic service does not receive the Rule 6(d) three-day addition. The selected court, local rules, orders, filing system and closure notices still require confirmation.
| Step | What is counted | Date |
|---|---|---|
| Service | Do not count this day | September 1, 2026 |
| Day 1 | Start counting calendar days | September 2, 2026 |
| Day 30 | Ordinary deadline in this example | October 1, 2026 |
Can an order, motion or extension change the deadline?
- Extensions
- Variable by stipulation under FRCP 29 or by court order; extendable under FRCP 6(b)(1). Untimely objections are generally waived under FRCP 33(b)(4) absent good cause.
- Orders and local rules
- A scheduling order, stipulation approved by the court, standing order or local rule can set a different period and controls over the national default.
- An early Rule 34 request can use the first Rule 26(f) conference as its trigger.
- A stipulation or court order can set another response period.
What should I check before filing?
These checks help you review the result. They do not activate a calendar date or certify that the deadline applies.
Common questions
Find answers about when this 30-day period starts, how it is counted, what can change it and how to keep your calculation.
Starting the clock
Does the clock start on the service of the selected discovery request, or when I first learned of it?
The period runs from the service of the selected discovery request as the rule defines it, not from the day you read about it, received a courtesy copy or attended a hearing. Use the date shown on the docket or in the service record.
Read Rule 33Do I add three days because the paper was served by mail?
FRCP 6(d) adds three days only after the listed non-electronic methods of service, such as mail. Electronic service through the court’s filing system does not add days. Check how service was actually made before adding anything.
FRCP 6(d)Counting days and filing
Is it 30 calendar days or business days?
Calendar days. Count intermediate weekends and holidays. If the final day is a Saturday, Sunday or legal holiday, FRCP 6(a) carries it forward to the next day that is not one of those.
FRCP 6(a)Which time zone and filing cutoff apply?
Under FRCP 6(a)(4), electronic filing ends at midnight in the court’s time zone unless a statute, local rule or court order sets a different time. Paper filing ends when the clerk’s office is scheduled to close. This calculator does not verify either fact.
FRCP 6(a)What if the court is inaccessible on the last day?
FRCP 6(a)(3) extends the period to the first accessible day that is not a weekend or legal holiday when the clerk’s office is inaccessible on the last day. Check the court’s closure notices and orders. A national holiday calculation does not establish an outage or local closure.
FRCP 6(a)Extensions and local rules
Can the court extend this deadline?
Variable by stipulation under FRCP 29 or by court order; extendable under FRCP 6(b)(1). Untimely objections are generally waived under FRCP 33(b)(4) absent good cause. A request does not itself extend the period, and no discretionary extension is calculated here.
Read Rule 33Do local rules, standing orders or a scheduling order change the date?
They can. Many courts set their own periods by local rule, standing order or case-specific order, and those control over the national default. This calculator gives the national-rule date only; compare it with any order in the case before relying on it.
Choosing the right calculator
Does this calculator decide whether the rule applies to my case?
No. It calculates a period from the date you provide under the cited rule. It does not decide whether the rule governs your filing, whether an exception applies, or whether the filing has merit. Those questions need separate review.
Can I calculate the deadline without an account?
Yes. Enter the trigger date to see the free national-rule calculation, citation, counting steps and warnings. You can add court context after the result. Missing court review keeps the result provisional.
Results, records and your case
What is included in an Evidence Record?
The retained inputs, result, cited rule, calculation working, warnings and review state. The PDF includes a payload digest and retained-data appendix, and the record can be verified against its fingerprint later. It records the calculation, not a guarantee of legal correctness.
Does saving to a case activate the calendar?
Not automatically. Provisional records remain subject to review. A separately labeled manual date does not alter the original calculation.
