Computes calendar-day deadlines under TRCP 4 (exclude the first day, include the last; roll forward off Saturdays / Sundays / legal holidays), applies the TRCP 21a +3-day service add-on, applies the TRCP 99 Monday rule for the answer, rolls off the Tex. Gov't Code § 662.003 legal holidays, and maps named rules to days plus authority via scripts/case-calendar.py.

Texas Case Deadlines
NOT LEGAL ADVICE. This skill computes deadlines. Independently
verify in the cited rule or statute, confirm the venue's local rules
and any docket-control or scheduling order, and treat no computed
date as final without checking.
Use this skill to compute deadlines under TRCP 4 (time
computation), the Texas legal-holiday list (Tex. Gov't Code
§ 662.003), and the named rules across the Texas Rules of Civil
Procedure and the Texas codes. The arithmetic lives in
scripts/case-calendar.py; this body is the framework and the pointer
to authority. Pull verbatim rule text from
../tx-law-references/references/court-rules/.
Time computation — TRCP 4
To count a period stated in days in the Texas Rules of Civil Procedure,
a court order, or (unless otherwise provided) a statute:
- Exclude the day of the act, event, or default that begins the
period (e.g., the date of service).
- Count every intervening day, including weekends and holidays.
- Include the last day of the period, unless it is a
Saturday, Sunday, or legal holiday — in which case the period
runs to the end of the next day that is none of those.
Confirm every day count below against the verbatim TRCP 4 text in the
corpus before treating any computed date as final.
The +3-day service add-on — TRCP 21a
When a period runs from service of a paper and service was made by
one of the methods that triggers the add-on (e.g., mail, commercial
delivery, fax, or email — the exact list is drift-prone), TRCP 21a
adds 3 days to the period. Apply the add-on after the
underlying TRCP 4 count. Confirm the current TRCP 21a add-on triggers
against the corpus — which service methods carry the +3 days is
amended periodically.
★ The answer deadline — the Monday rule — TRCP 99
★ The answer is not due a flat number of days after service. In
District Court and County Court at Law, TRCP 99 sets the answer
due by 10:00 a.m. on the Monday next after the expiration of 20
days after the date of service. Count 20 days from service; the
answer is then due at 10:00 a.m. on the next Monday following.
Compute it with --rule answer-due. Justice Court answers run on a
different clock — by the end of the 14th day after service (TRCP
502.5) — use --rule answer-due-justice. See tx-first-30-days.
Texas legal holidays — Tex. Gov't Code § 662.003
The holidays that trigger the TRCP 4 roll-forward are the national
holidays in Tex. Gov't Code § 662.003, on which the courts are
closed. The list below is qualitative; the authoritative,
year-by-year computed set lives in scripts/case-calendar.py and the
corpus — confirm there before relying on a date.
| Holiday | Date rule |
|---|
| New Year's Day | January 1 (fixed) |
| Martin Luther King, Jr., Day | 3rd Monday in January |
| Presidents' Day / Washington's Birthday | 3rd Monday in February |
| Memorial Day | Last Monday in May |
| Juneteenth National Independence Day | June 19 (fixed) |
| Independence Day | July 4 (fixed) |
| Labor Day | 1st Monday in September |
| Veterans Day | November 11 (fixed) |
| Thanksgiving Day | 4th Thursday in November |
| Friday after Thanksgiving | Day after the 4th Thursday in November |
| Christmas Day | December 25 (fixed) |
Texas specifics to flag. Texas courts observe Juneteenth
National Independence Day (June 19) and the Friday after
Thanksgiving as court-closed national holidays — roll forward off
both. Texas also designates "partial-staffing" state holidays
(Confederate Heroes Day, Texas Independence Day, San Jacinto Day, LBJ
Day) on which state offices run with reduced staff but courts
generally do NOT close — do not roll a deadline forward off a
partial-staffing day. Confirm the operative court-closed set in the
corpus / script.

Answer, notice, and discovery day counts are stable enough to state
in this body as framework anchors; statute-of-limitations periods are
computed on the calendar (anniversary date), so cite the section and
verify the current period. Always confirm against the corpus / script.

# Ad hoc count — 30 calendar days from service, with roll-forward
python3 scripts/case-calendar.py --from 2026-04-01 --days 30 --mode calendar
For a period that runs from service by a TRCP 21a add-on method, add
the 3-day add-on after the underlying TRCP 4 count.
Statutes of limitations — point at the codes, do not embed counts
Texas's civil limitations periods are computed on the calendar
(anniversary) date, not as a fixed day count. Cite the section and
verify the current period rather than hard-coding it here:
| Claim family | Period | Authority |
|---|
| Debt / breach of contract | 4 years | CPRC § 16.004 |
| Residual (no other period set) | 4 years | CPRC § 16.051 |
| Personal injury / tort | 2 years | CPRC § 16.003 |
| DTPA | 2 years | Tex. Bus. & Com. Code § 17.565 |
| Fraud / debt (discovery rule may apply) | varies | confirm against the corpus |
| Action on / dormancy of a judgment | 10 years | CPRC § 34.001 (and revival § 31.006) |
| Federal — FDCPA | 1 year | 15 U.S.C. § 1692k(d) (federal corpus) |
| Federal — FCRA / TILA | see corpus | federal corpus |
Time-barred consumer debt is not revived by a partial payment.
Under Tex. Fin. Code § 392.307 (and the written-acknowledgment
rule, CPRC § 16.065), a payment on out-of-statute consumer debt
does not restart Texas limitations, and the collector owes a
statutory notice — a strong defense (see tx-consumer-debt). SOL
accrual, tolling, and any revival are fact-dependent — verify
against current law for the specific claim.
Appeal and post-judgment windows to watch
- Motion for new trial / to modify, correct, or reform — TRCP 329b.
File within 30 days after the judgment is signed (not entered)
— TRCP 329b(a), (g). A timely such motion extends the court's
plenary power and the appellate timetable. See
tx-post-judgment.
- Plenary power — TRCP 329b(d). The trial court retains plenary
power to vacate, modify, correct, or reform the judgment for 30
days after signing, extended by a timely post-judgment motion.
- Notice of Appeal — Tex. R. App. P. 26.1. File within 30 days
after the judgment is signed, or 90 days if any party timely
files a motion for new trial, to modify, to reinstate, or a request
for findings of fact. Confirm which event triggers the clock.
How tx-deadlines composes with the scripts
The arithmetic lives in scripts/case-calendar.py, which encodes the
Tex. Gov't Code § 662.003 court-closed holidays for any year,
applies the TRCP 4 roll-forward off Saturdays / Sundays / holidays, the
TRCP 21a 3-day add-on, and the TRCP 99 Monday-rule answer computation,
and maps named rule keys to (days, mode, description, authority).
Confirm the script's holiday set and rule counts against
../tx-law-references/references/court-rules/ after any quarterly
corpus refresh.
