This is one of the most common questions in litigation practice, and the answer surprises people who learned the old rule. The short version: in federal court you count weekends and holidays, but you never let a filing come due on one. Here is how Rule 6(a) actually works, step by step. This is general information about how the federal method is structured, not legal advice; always confirm against the rule and any local or standing order that applies to your case.
The federal method: FRCP 6(a) in three steps
Rule 6(a)(1) governs any period stated in days. It breaks into three parts, and getting them in the right order is the whole game.
Step 1: exclude the trigger day
Rule 6(a)(1)(A) says to exclude the day of the event that starts the clock. If you are served on the 3rd, day one of the period is the 4th, not the 3rd. The triggering day itself never counts.
Step 2: count every day, weekends and holidays included
Rule 6(a)(1)(B) says to count every day after that, including intermediate Saturdays, Sundays, and legal holidays. A 21-day period is 21 calendar days. You do not skip the weekends in the middle. This is the part people get wrong, because the pre-2009 rule did skip them for short periods.
Step 3: roll the last day off any weekend or holiday
Rule 6(a)(1)(C) is the safety valve. If the last day of the count falls on a Saturday, Sunday, or legal holiday, the period continues until the end of the next day that is not one of those. So you count through weekends, but the deadline itself always lands on a business day. The rule also treats a day when the clerk's office is inaccessible (for weather or another reason) like a holiday for this purpose.
Why so many people skip weekends (and why that is wrong now)
Before December 1, 2009, Rule 6(a) told you to exclude intermediate weekends and holidays whenever the period was less than 11 days. That produced a confusing split: short deadlines counted business days, long deadlines counted calendar days. The 2009 time-computation amendments abolished that distinction. Every day-period now counts every day. If you were trained before 2009, or you learned from someone who was, the instinct to skip weekends on a five-day deadline is a habit worth unlearning. It will now make your deadline later than the rule allows.
A worked example
Say a rule gives you 14 days to respond and the triggering event happens on Friday, July 3, 2026 (with the Fourth of July observed as a federal holiday). Here is the count.
| Step | What you do | Result |
|---|---|---|
| Trigger | Event occurs; do not count this day | Fri, Jul 3, 2026 |
| Day 1 | Start counting the next day | Sat, Jul 4 (counts, even as a weekend and holiday) |
| Day 14 | Count 14 calendar days total | Fri, Jul 17, 2026 |
| Adjust | Last day is a business day, so no roll | Deadline: Fri, Jul 17, 2026 |
If that fourteenth day had landed on a Saturday, the deadline would move to the following Monday (or Tuesday, if Monday were a holiday). You can run any date through our court date calculator, which applies the Rule 6 method and the observed federal holidays automatically.
State courts do not all follow the federal rule
The federal calendar-day method is not universal. Many states track it, but several use a "court day" system for shorter deadlines, where weekends and holidays are excluded from the count entirely. California is the best-known example: its Code of Civil Procedure counts court days for many motion deadlines, so a five-court-day notice period genuinely skips the weekend. If your matter is in state court, check that state's time-computation statute and local rules before you rely on the federal method. A deadline that is correct in federal court can be wrong down the street. Firms litigating in more than one forum usually stop counting by hand at that point and move the rule sets into legal calendaring and docketing software, which applies the right jurisdiction's time computation per matter.
Administrative and specialist forums add a third counting convention on top of both. Immigration practice is the sharpest example, where a 30-day appeal window to the BIA is jurisdictional and does not roll for the reasons a district-court deadline does, which is why immigration case management software tracks filing windows separately from the litigation calendar. Family law sits at the other end: family law case management software has to carry statutory waiting periods and service deadlines that run in calendar days regardless of what the motion calendar says.
Counting court deadlines, common questions
Do you count the day you were served?
No. Under FRCP 6(a)(1)(A), you exclude the day of the triggering event, including the day of service. Counting starts on the next day. So if you are served on a Monday and have 21 days to answer, Tuesday is day one and you count 21 days from there.
What happens if a court deadline falls on a weekend or holiday?
The deadline extends to the next day that is not a Saturday, Sunday, or legal holiday. Under FRCP 6(a)(1)(C), you still count through the intermediate weekends and holidays, but a period can never actually end on one. If your fourteenth day is a Sunday, the filing is due Monday; if Monday is also a holiday, it is due Tuesday.
Do you count weekends for a 5-day or 7-day deadline?
Yes, in federal court. Since the 2009 amendments, there is no separate rule for short periods, so a 5-day or 7-day deadline counts intermediate weekends and holidays just like a longer one. The old rule that excluded weekends for periods under 11 days no longer applies. Note that some state courts still use court-day counting for short deadlines, so confirm the forum.
How are deadlines stated in hours computed?
Rule 6(a)(2) handles periods stated in hours. You begin counting immediately on the occurrence of the triggering event, count every hour including those on weekends and holidays, and if the period would end on a Saturday, Sunday, or legal holiday, it runs until the same time on the next business day. Hour-based deadlines are less common but follow the same count-through, roll-the-end logic.
