Why this page does not calculate a date
Stated separately from the finality limb rather than merged. Constructive, not actual, discovery. No ultimate long-stop: section 2255 contains no repose period, so this limb can accrue long after conviction became final.
Read 28 USC 2255"the date on which the facts supporting the claim or claims presented could have been discovered through the exercise of due diligence"
28 U.S.C. 2255(f)(4)
Which date starts the 1 year period?
The period runs from the date on which the facts supporting the claim could have been discovered through the exercise of due diligence.
Count forward from the trigger event. Confirm the event on the docket or in the service record before entering a date.

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 1 year 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 trigger day and count calendar days under FRCP 6(a).
If the final day is a Saturday, Sunday or legal holiday, FRCP 6(a) carries it to the next open day.
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.
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.
Stated separately from the finality limb rather than merged. Constructive, not actual, discovery. No ultimate long-stop: section 2255 contains no repose period, so this limb can accrue long after conviction became final.
Can an order, motion or extension change the deadline?
- Extensions
- Equitable tolling on the Holland standard.
- 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 1 year 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 date on which the facts supporting the claim could have been discovered through the exercise of due diligence, or when I first learned of it?
The period runs from the date on which the facts supporting the claim could have been discovered through the exercise of due diligence 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 28 USC 2255Do I add three days because the document arrived by mail?
Not to this period. FRCP 6(d) concerns periods measured after service. This period runs from the date on which the facts supporting the claim could have been discovered through the exercise of due diligence, so no mailing days are added.
FRCP 6(d)Counting days and filing
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?
Equitable tolling on the Holland standard. A request does not itself extend the period, and no discretionary extension is calculated here.
Read 28 USC 2255Do 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.
