What Is a Business Day in Court Filings?

Court rules rarely count in business days. The Federal Rules of Civil Procedure in the United States count every day and look at the calendar only on the last one; the Civil Procedure Rules of England and Wales count "clear days" and leave weekends out of the shortest periods alone. This guide sets out what each rule's text says, with dates worked for 2026, and adds what the California Rules of Court say about counting time and electronic filing. It describes the rules and is not legal advice: a statute, a local rule or a court order can set a different time.

Federal Rule 6(a): every day counts

Rule 6(a) of the Federal Rules of Civil Procedure applies, in its own words, "in computing any time period specified in these rules, in any local rule or court order, or in any statute that does not specify a method of computing time". For a period stated in days or a longer unit, Rule 6(a)(1) gives three steps:

1. Exclude the day of the event that triggers the period.
2. Count every day, including intermediate Saturdays, Sundays and legal holidays.
3. Include the last day of the period. If that day is a Saturday, Sunday or legal holiday, the period continues to run until the end of the next day that is none of those.

So a 14-day period triggered on Monday, June 1, 2026 ends on Monday, June 15, 2026, and a 30-day period from the same day ends on Wednesday, July 1, 2026. Neither count skips a weekend. The calendar matters at the end only: ten days from Wednesday, June 3, 2026 end on Saturday, June 13, 2026, so that period runs to Monday, June 15, 2026.

The rule has not always worked this way. The Advisory Committee's note to the 2009 amendment records that, under the former rule, a period of less than 11 days left out intermediate Saturdays, Sundays and legal holidays while a period of 11 days or more included them. Since that amendment the count is the same at every length.

The same note draws a line that is easy to miss. Rule 6(a) applies when a period has to be computed. Where a court sets a fixed date (the note's example is a filing due "no later than November 1, 2007") there is nothing to count, and the rule does not govern.

Hours, the last day and legal holidays

Rule 6(a)(2) covers a period stated in hours. Counting begins immediately when the triggering event occurs, every hour counts, including hours on intermediate Saturdays, Sundays and legal holidays, and a period that would end on one of those days runs until the same time on the next day that is not.

When does the last day end? Rule 6(a)(4) answers: unless a statute, local rule or court order sets a different time, for electronic filing at midnight in the court's time zone, and for filing by other means when the clerk's office is scheduled to close. The clock is the court's, wherever the filer sits.

"Legal holiday" is defined in Rule 6(a)(6). It means the day set aside by statute for observing one of eleven named federal holidays, from New Year's Day to Christmas Day; any day declared a holiday by the President or Congress; and, for periods measured after an event, any other day declared a holiday by the state where the district court is located. Take a 21-day period triggered on Friday, May 29, 2026. Its last day is Friday, June 19, 2026, which is Juneteenth, one of the eleven, so the period runs to Monday, June 22, 2026.

A court that is closed on an ordinary day falls under a different provision. Under Rule 6(a)(3), if the clerk's office is inaccessible on the last day for filing, the time for filing is extended to the first accessible day that is not a Saturday, Sunday or legal holiday, unless the court orders otherwise.

Three more days after some kinds of service

Rule 6(d) adds three days when a party must act within a specified time after being served and service was made in one of three ways listed in Rule 5(b)(2): by mail (C), by leaving the paper with the court clerk when the person has no known address (D), or by other means the person consented to (F). The three days are added after the period would otherwise expire under Rule 6(a).

Electronic service is not on that list. The note to the 2016 amendment says Rule 6(d) was amended to remove service by electronic means under Rule 5(b)(2)(E) from the modes of service that allow three added days.

The note to the 2005 amendment explains the order of the steps: find the day the period expires under Rule 6(a), add three days, counting intermediate weekends and holidays, and if the third day is a Saturday, Sunday or legal holiday, the last day to act is the next day that is not. For the 21-day period above, which runs to Monday, June 22, 2026, service by mail moves the last day to Thursday, June 25, 2026.

England and Wales: clear days

Rule 2.8 of the Civil Procedure Rules shows how to calculate a period specified by the Rules, by a practice direction, or by a judgment or order of the court. A period expressed as a number of days is computed as clear days: the day on which the period begins is not included, and nor, if the end of the period is defined by reference to an event, is the day on which that event occurs.

Weekends drop out of short periods only. Under rule 2.8(4), where the specified period is 5 days or less and includes a Saturday or Sunday, or a Bank Holiday, Christmas Day or Good Friday, that day does not count. The rule gives its own example: notice of an application must be served at least 3 days before the hearing, the application is to be heard on Monday 20 October, and the last date for service is Tuesday 14 October. A period of more than five days gets no such treatment.

Rule 2.8(5) deals with a closed court office. When the period for doing any act at the court office ends on a day on which the office is closed, the act is in time if it is done on the next day on which the office is open.

Service has its own vocabulary. In Part 6, "business day" means any day except Saturday, Sunday, a bank holiday, Good Friday or Christmas Day, and "bank holiday" means one in the part of the United Kingdom where service is to take place. A claim form served within the United Kingdom is deemed served on the second business day after completion of the relevant step under rule 7.5(1) (rule 6.14). If that step is completed on Thursday, April 2, 2026, the day before Good Friday, the second business day in England and Wales is Wednesday, April 8, 2026. For other documents the table in rule 6.26 sets the day by method: an e-mail sent on a business day before 4.30pm is deemed served that day, and in any other case on the next business day.

Electronic filing has its own practice direction. Practice Direction 5C, which supplements rules 5.5 and 7.12, governs CE-File, the electronic filing system of the courts it lists. It fixes the moment of filing by what was submitted. Where a document requires a fee, "the date and time of filing is the date and time when the fee is paid" (paragraph 3.5(1)), with separate provision for the Administrative Court, the Court of Appeal and insolvency filings that need a deposit. For all other submissions, the date and time of filing is the date and time of submission stated on the automated submission confirmation, unless the court expressly provides otherwise (paragraph 3.5(5)). A submission that is rejected and made again takes the date and time of the new one (paragraph 3.4(4)).

California: what the Rules of Court say

California's statutes on computing time and on electronic filing sit in its Code of Civil Procedure, which this guide could not read at its official source and does not quote. The California Rules of Court, published by the state's judicial branch, are readable. Rule 1.10(a) computes the time for any act provided by those rules "by excluding the first day and including the last, unless the last day is a Saturday, Sunday, or other legal holiday, and then it is also excluded". Under rule 1.10(b), unless otherwise provided by law, a period ending on such a day "is extended to and includes the next day that is not a holiday". Both paragraphs govern time under the rules, not time fixed by a statute.

For electronic filing, rule 2.253(b)(6) says the effective date of filing a document received electronically is prescribed by Code of Civil Procedure section 1010.6. Rule 2.259(a) covers the proof. The court must promptly confirm receipt with the date and time, a document "is considered received at the date and time the confirmation of receipt is created", and the later filing confirmation "is proof that the document was filed on the date and at the time specified". Without the court's confirmation there is no presumption that the document was received and filed, and the filer is responsible for checking. If a technical problem with the court's system prevents it from accepting a filing on a court day and the filer shows an attempt that day, the court must deem the document filed that day, except for a complaint or other initial pleading (rule 2.259(c)). Rule 3.1300(c) counts in court days: proof of service of the moving papers must be filed no later than five court days before the hearing.

Which calculator fits which rule

A Rule 6(a) period is a calendar-day count with a check on the last day, so Add Business Days gives the wrong answer for it. Use the response deadline calculator set to calendar days with the United States selected: it leaves out the trigger day, counts every day and, when the last day is a weekend or a federal holiday, shows the next business day beside it. It does not know a state holiday under Rule 6(a)(6)(C), a closed clerk's office or a local rule, so check those yourself.

A CPR period of five days or less is a business-day count. For that, and for the "second business day" of rule 6.14, use Add Business Days with the UK calendar. Longer clear-day periods are plain calendar counts, which Calendar Days from Today covers.

Limitation periods are a different question from deadlines inside a case. The guide to statutes of limitations and business days takes them up.

FAQ

Does Federal Rule 6 count weekends in a deadline?

Yes, for every period stated in days. Rule 6(a)(1)(B) says to count every day, including intermediate Saturdays, Sundays and legal holidays, after the day of the triggering event is excluded under Rule 6(a)(1)(A). Weekends matter on the last day only: under Rule 6(a)(1)(C) a period whose last day is a Saturday, Sunday or legal holiday runs until the end of the next day that is none of those. Before the 2009 amendment, periods of less than 11 days left weekends out.

At what time does the last day of a federal deadline end?

Rule 6(a)(4) sets it: for electronic filing, at midnight in the court's time zone; for filing by other means, when the clerk's office is scheduled to close. A statute, local rule or court order can set a different time, so read the local rules of the court you are filing in.

Does the 3-day rule apply to electronic service?

No. Rule 6(d) adds 3 days after service by mail, by leaving the paper with the clerk, or by other means consented to: Rule 5(b)(2)(C), (D) and (F). The 2016 amendment removed electronic service under Rule 5(b)(2)(E) from that list. The three days are added after the period would otherwise expire under Rule 6(a).

What is a business day under the Civil Procedure Rules of England and Wales?

For service under Part 6, any day except Saturday, Sunday, a bank holiday, Good Friday or Christmas Day. For counting time, rule 2.8 uses clear days, and only a period of 5 days or less leaves out Saturdays, Sundays, Bank Holidays, Christmas Day and Good Friday.
