Why this page does not calculate a date
Four alternative triggers depending on rehearing history and, for Rule 23 orders, on any motion to publish. Establish the Appellate Court's procedural history before computing.
Read Illinois Supreme Court RulesUnless a timely petition for rehearing is filed in the Appellate Court, a party seeking leave to appeal must file the petition for leave in the Supreme Court within 35 days after the entry of such judgment. If a timely petition for rehearing is filed, the party seeking review must file the petition for leave to appeal within 35 days after the entry of the order denying the petition for rehearing or, if a modified decision is issued upon denial of rehearing, from the entry of the modified decision. If a petition is granted, the petition for leave to appeal must be filed within 35 days of the entry of the judgment on rehearing.
Ill. S. Ct. R. 315(b)(1)
Which date starts the 35-day period?
The period runs from the entry of the Appellate Court judgment, or entry of the order denying a timely petition for rehearing, or entry of a modified decision issued on denial of rehearing, or entry of the judgment on rehearing.
Count forward from the trigger event. Confirm the event on the docket or in the service record before entering a date.

This is a docket-entry calculation. Do not substitute the day an email arrived, the day you read the order or the day of the hearing.
Which date do I enter?How are the 35 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 Illinois legal holiday, continue to the next day that is not one of those.
Exclude the trigger day and count calendar days under 5 ILCS 70/1.11 (Statute on Statutes, Computation of time).
If the final day is a Saturday, Sunday or legal holiday in the Illinois calendar, the computation rule carries it to the next open day.
Illinois computes time under 5 ILCS 70/1.11 (Statute on Statutes, Computation of time). The applied calendar bundles the state legal holidays for the covered years; court-specific closures and emergency orders are not bundled.
Read 5 ILCS 70/1.11 (Statute on Statutes, Computation of time)The calculation gives the ordinary national-rule date. Check relevant holidays, the court’s accessibility and its filing cutoff separately.

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 Supreme Court or a judge may extend the time on motion, but such motions are not favored and will be allowed only in the most extreme and compelling circumstances. Do not compute.
- 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 35-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 entry of the Appellate Court judgment, or entry of the order denying a timely petition for rehearing, or entry of a modified decision issued on denial of rehearing, or entry of the judgment on rehearing, or when I first learned of it?
The period runs from the entry of the Appellate Court judgment, or entry of the order denying a timely petition for rehearing, or entry of a modified decision issued on denial of rehearing, or entry of the judgment on rehearing 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
Is it 35 calendar days or business days?
Calendar days. Count intermediate weekends and holidays. If the final day is a Saturday, Sunday or legal holiday, 5 ILCS 70/1.11 (Statute on Statutes, Computation of time) carries it forward to the next day that is not one of those.
5 ILCS 70/1.11 (Statute on Statutes, Computation of time)Which time zone and filing cutoff apply?
Illinois filing rules and the court’s electronic filing system set the cutoff. This calculator does not verify filing hours or system availability.
5 ILCS 70/1.11 (Statute on Statutes, Computation of time)What if the court is inaccessible on the last day?
5 ILCS 70/1.11 (Statute on Statutes, 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.
5 ILCS 70/1.11 (Statute on Statutes, Computation of time)Extensions and local rules
Can the court extend this deadline?
The Supreme Court or a judge may extend the time on motion, but such motions are not favored and will be allowed only in the most extreme and compelling circumstances. Do not compute. 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
