Plain-English Summary
Rule 2.2 gives the method for computing any time period set by the rules, a local rule, a court order, or a statute that doesn't specify its own method. Skip the day of the triggering event, then count every day after it — including Saturdays, Sundays, and legal holidays — up to and including the last day. If that last day lands on a Saturday, Sunday, or legal holiday, the period runs until the end of the next day that isn't one. If the clerk's office is inaccessible on what would be the deadline, the time extends to the next accessible day that isn't a weekend or holiday, unless the court orders otherwise.
The rule then addresses extensions. A court may extend a deadline for good cause, either before the original deadline (or an earlier extension) expires — with or without a motion — or after it has already expired if the party shows excusable neglect for missing it. Parties can also agree in writing to extend a deadline themselves, as long as the extension doesn't interfere with the court's schedule. That flexibility has real limits, though: a court cannot extend the time to act under Rules 50(b), 52(b), 59(b), (d), and (e), or 60(b), all of which involve post-trial motions where firm deadlines protect the finality of a judgment.
Finally, when a party must act within a set time after being served by mail, Rule 2.2 adds three extra days to that time to account for mailing delay.
Frequently Asked Questions
Do weekends and holidays count toward a filing deadline in Idaho?
Yes, every day counts, but if the deadline itself falls on a Saturday, Sunday, or legal holiday, it rolls forward to the end of the next day that isn't one.
Can I get more time to file something after my deadline has already passed?
Yes, if you show excusable neglect for missing it, a court can extend the time on motion made after expiration — except for the post-trial motions listed as exceptions in Rule 2.2(b)(3).
Which deadlines can never be extended by the court?
Rules 50(b), 52(b), 59(b), (d), and (e), and 60(b) — all post-trial motion deadlines — are excluded from the court's power to extend time.
If I was served by mail, do I get extra time to respond?
Yes, three days are added to whatever time period you would otherwise have.
Can the parties just agree between themselves to extend a deadline?
Yes, by written stipulation, filed before or after the deadline, as long as it doesn't disturb the orderly dispatch of court business.
