What is the deadline for service of an application for an order or notice of a court proceeding?
Service of an application for an order or notice of a court proceeding is governed by TRCP 21(b). This page does not calculate a date. Genuine ambiguity. Read the rule text and the noted conditions before relying on any date.

Why this page does not calculate a date
Genuine ambiguity. TRCP 4 excepts "the three-day periods in Rules 21 and 21a, extending other periods by three days when service is made by mail" from the short-period exclusion. The better reading is that the exception targets only the mail add-on (now in TRCP 21a(c)), leaving the TRCP 21(b) notice period as a working-day count, but the literal reference to "Rules 21 and 21a" is capable of the opposite reading. Confirm against local practice before relying on it.
Read Texas Judicial Branch rules and standards"An application to the court for an order and notice of any court proceeding, as defined in Rule 21d(a), not presented during a court proceeding, must be served upon all other parties not less than three days before the time specified for the court proceeding, unless otherwise provided by these rules or shortened by the court." (TRCP 21(b))
TRCP 21(b)
Which date starts the 3 working-days period?
The period runs from the time specified for the court proceeding (counted backwards).
Count backward from the trigger event. Confirm the event on the docket or in the service record before entering a date.

TRCP 21(b)
This period runs from the specific event in the cited rule. Do not substitute a nearby date such as a hearing, a courtesy copy or the day you first learned of it.
Which date do I enter?How are the 3 working-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 Texas legal holiday, continue to the next day that is not one of those.
Exclude the trigger day and count calendar days under Tex. R. Civ. P. 4 (Computation of Time).
If the final day is a Saturday, Sunday or legal holiday in the Texas calendar, the computation rule carries it to the next open day.
Texas computes time under Tex. R. Civ. P. 4 (Computation of Time). The applied calendar bundles the state legal holidays for the covered years; court-specific closures and emergency orders are not bundled.

Review the filing checklistWhy no worked calculation is shown
No date is calculated on this page because the encoded provision could not be reduced to one fixed period. Read the rule text, the starting event and the noted branches, then confirm the period in the current rules before relying on any date.

Can an order, motion or extension change the deadline?
- Extensions
- The court may shorten the period (TRCP 21(b)); other rules may provide otherwise.
- 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.

Common questions
Find answers about when this 3 working-days 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 time specified for the court proceeding (counted backwards), or when I first learned of it?
The period runs from the time specified for the court proceeding (counted backwards) 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.
Counting days and filing
Which time zone and filing cutoff apply?
Texas filing rules and the court’s electronic filing system set the cutoff. This calculator does not verify filing hours or system availability.
Tex. R. Civ. P. 4 (Computation of Time)What if the court is inaccessible on the last day?
Tex. R. Civ. P. 4 (Computation of Time) and the court’s administrative orders govern an inaccessible clerk’s office. Check the court’s notices. This calculator does not predict a closure.
Tex. R. Civ. P. 4 (Computation of Time)Extensions and local rules
Can the court extend this deadline?
The court may shorten the period (TRCP 21(b)); other rules may provide otherwise. A request does not itself extend the period, and no discretionary extension is calculated here.
Do 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.
Official sources and review
The period and the counting method come from different provisions. The official source is the court’s published rules; the reading links open the rule text at the Legal Information Institute.
