How do I compare the Illinois joining, separate-appeal and cross-appeal periods?

Establish that the preceding notice was timely filed and served.

Establish the effective service event under Rule 12 and the actual applicable judgment or last pending qualifying ruling.

Compare the rule’s applicable ten-day and thirty-day boundaries, or establish the separate late-notice-order branch.

1. Establish that the preceding notice was timely filed and served.
2. Exclude the independently established triggering day and count intermediate calendar days under 5 ILCS 70/1.11. A filing, entry, effective service or previously established due date must come from its actual record. Do not substitute one event for another. Compute each applicable limb separately before choosing the later boundary.
3. Check statutory holidays and the proper court’s actual calendar.
4. Complete the particular act in the proper court.

Section 1.11 excludes a final Saturday, Sunday or statutory holiday and consecutive excluded days. Section 17(a) of the Promissory Note and Bank Holiday Act includes Pulaski Day, Good Friday and the general election for members of the House of Representatives. Check proclamations, the proper court’s actual calendar and clerk access separately. The bundled Illinois calendar covers 2026 and 2027.

This question requires multiple actual events, effective service and the applicable later-of or late-notice-order branch. The isolated preset cannot establish the complete result.

Only a timely qualifying motion changes the ordinary trigger

Rule 303(a)(1) requires a timely posttrial motion directed against the judgment. Use the order disposing of the last pending qualifying motion, not an earlier motion’s disposition or the filing date. Rule 303(a)(2) says a request to reconsider a ruling on a postjudgment motion does not toll the appeal time.

Effective service must be established

Use Rule 11’s applicable service method and file Rule 12 proof. Rule 12(c) makes electronic or personal delivery service effective on its stated day, mail service complete four days after mailing, and third-party carrier service complete on the third court day after delivery to the carrier. Establish effective service before using a service-triggered calculator. A rule requiring personal or email service cannot be replaced with ordinary mail.

A permitted late notice has its own event

When the reviewing court grants late-notice permission, Rule 303(d) allows another party ten days from that actual order to join, appeal separately or cross-appeal. Do not substitute the late notice’s filing or service date.

The notice must identify the judgment and relief

Rule 303(b) requires the appeal court, originating circuit court, case title and party designations, appropriate notice designation, appealed judgment or parts and requested relief, and appellant or attorney name and address. Its constitutional-judgment branch requires the stated Rule 18 findings attachment.

Filing, service and clerk transmission are different obligations

Rule 303(c) requires the filing party’s notice of filing in the reviewing court and service on every other party and each person or officer entitled by law within seven days, with Rule 12 proof filed with the notice. Rule 303(a)(4) separately requires the circuit clerk to file the notice or covered amendment with the reviewing clerk within five days.

• The calculator does not decide appealability, disputed facts, sufficiency of a filing or whether the court grants relief.
• Check the governing edition and actual orders. A current rule does not establish every historical appeal’s timetable.

• Establish that the preceding notice was timely filed and served.
• Establish the effective service event under Rule 12 and the actual applicable judgment or last pending qualifying ruling.
• Compare the rule’s applicable ten-day and thirty-day boundaries, or establish the separate late-notice-order branch.
• Rule 303(a)(1) requires a timely posttrial motion directed against the judgment. Use the order disposing of the last pending qualifying motion, not an earlier motion’s disposition or the filing date. Rule 303(a)(2) says a request to reconsider a ruling on a postjudgment motion does not toll the appeal time.
• Use Rule 11’s applicable service method and file Rule 12 proof. Rule 12(c) makes electronic or personal delivery service effective on its stated day, mail service complete four days after mailing, and third-party carrier service complete on the third court day after delivery to the carrier. Establish effective service before using a service-triggered calculator. A rule requiring personal or email service cannot be replaced with ordinary mail.
• When the reviewing court grants late-notice permission, Rule 303(d) allows another party ten days from that actual order to join, appeal separately or cross-appeal. Do not substitute the late notice’s filing or service date.
• Rule 303(b) requires the appeal court, originating circuit court, case title and party designations, appropriate notice designation, appealed judgment or parts and requested relief, and appellant or attorney name and address. Its constitutional-judgment branch requires the stated Rule 18 findings attachment.
• Rule 303(c) requires the filing party’s notice of filing in the reviewing court and service on every other party and each person or officer entitled by law within seven days, with Rule 12 proof filed with the notice. Rule 303(a)(4) separately requires the circuit clerk to file the notice or covered amendment with the reviewing clerk within five days.
• File the required notice with the circuit court clerk under Rule 303(a). Complete its required contents under Rule 303(b). Separately file the reviewing-court notice of filing and serve the required recipients with Rule 12 proof under Rule 303(c). Preserve the actual filing, entry and service records. Use the proper clerk and required filing format. Rule 9 ordinarily requires electronic filing in civil cases, subject to its exceptions and exemptions. Rule 9(f) ordinarily uses submission before midnight in the court time zone, unless a statute, rule or order sets a particular time. A submission when the clerk is closed is ordinarily stamped on the next open day. Current Rule 9(f) provides separate five-court-day motions for a rejected filing or qualifying technical failure; establish the actual notice, failure, corrected document and required proof. Rule 373 ordinarily uses actual receipt, with its mail or carrier exception limited to filings excepted or exempt from electronic filing. Its carrier branch requires delivery for receipt within three business days and Rule 12(b) proof. Filing and service remain separate acts.
