The Calendar

One day late

In February 2005, a medical practice called David M. Dresdner, M.D., P.A. lost its suit against its insurer over $125,285.82 in medical supplies, and it decided to appeal. The trial court denied a new trial on April 6, which gave the practice until Friday, May 6, to file its notice of appeal. A legal assistant in the appellate lawyer’s office apparently never put that date on the calendar. The notice went in on Monday, May 9, and the Second District dismissed the appeal. The trial court then found the mistake excusable, vacated its own order, and entered it again so that a new thirty days would run. The Second District reversed that too, holding that the trial court could not rescue the appeal “even though the lawyer’s error may be excusable.”

Dresdner (opens in a new tab) is a case about a calendar, and it shows both halves of the law on missed deadlines. The court agreed that an assistant’s oversight like this one can be excusable neglect, and still nothing could be done. So which missed deadlines can a court forgive, and what does the answer mean for how a firm keeps its calendar? This reading argues that the line runs in two places. Courts forgive a slip inside a system that works, not the lack of a system, and some deadlines cannot be forgiven at all. In the activity, you build the calendar for a case Temko Eden has just taken on.

Every deadline starts as a count

Almost no deadline in a lawsuit arrives as a date. A rule says twenty days after service, an order says ninety days before docket sounding, a statute says two years. Someone has to turn each period into a day on the calendar, and that arithmetic is the first place a deadline can go wrong.

In a Florida court, the arithmetic belongs to Rule 2.514, which governs any period in a court rule, a court order, or a statute that does not give its own method. Its method, the one the activity calls computing time under Rule 2.514, has a feature that surprises people. For a period of seven days or more, you begin counting on the next day that is not a Saturday, Sunday, or legal holiday. Then every day counts, and a last day that lands on a weekend or holiday rolls forward to the next day that is not one.

The federal rule starts differently. Federal Rule 6 excludes the day of the event and counts every day after it, Saturday included. Take a ten-day period that starts with an event on a Friday. In a Florida court, Monday is day one and the tenth day is the Wednesday of the next week. In a federal court, Saturday is day one and the tenth day is the Monday. Neither answer is wrong in its own court, so a deadline has to be counted under the rule of the court that set it. That includes a deadline for moving a case from one court to the other, since removal runs on a federal statute.

The courts do not share a holiday list either. Florida counts as a legal holiday any day the clerk’s office observes, and the Seventh Judicial Circuit, which covers Volusia County, closes for Good Friday and the Friday after Thanksgiving. The federal court in Orlando stays open on both, but it closes for Juneteenth and Columbus Day, which the circuit does not observe. Service matters too. Florida adds five days only when a paper is served by mail alone, and the federal rule adds three for mail, while service through the e-filing portal or by e-mail adds nothing in either court.

Some periods run backward. An order that wants expert disclosures ninety days before docket sounding is counting backward, and both rules say the next day is then the day before. So if the ninetieth day before lands on a Sunday, the disclosure is due the Friday before it. Monday would leave the other side less time than the order promised.

The counting rule reaches statutes as well, including statutes of limitations. In Herrero v. Black & Decker Manufacturing Co. (opens in a new tab), a two-year limitations period ended on a Sunday, and the Third District held that a suit filed on the Monday was on time. The Supreme Court of Florida adopted that decision the same year.

A slip inside a system, or no system at all

When a firm misses a deadline and the other side wins because of it, Florida Rule of Civil Procedure 1.540(b)(1) lets the court set the judgment or order aside for excusable neglect. The definition Florida courts keep quoting comes from a 1985 Fourth District case, Somero v. Hendry General Hospital (opens in a new tab). It covers clerical or secretarial error, reasonable misunderstanding, a system gone awry, and “any other of the foibles to which human nature is heir.” The same opinion stated the other side of the line: no relief where the party or its lawyer simply forgot, or ignored the need to act.

The phrase that matters for a calendar is “a system gone awry,” and it assumes a system. In Amerant Bank, N.A. v. D.R. Horton, Inc. (opens in a new tab), decided in 2026, a homebuilder’s legal department received a lawsuit through its registered agent. Its procedures called for calendaring a response date and sending the case to outside counsel, and neither happened. Its in-house lawyer went on leave earlier than planned, and the backup coverage failed too. A default final judgment followed. When the company found it and moved within a month, the trial court set the judgment aside, and the Third District affirmed. The system existed, and it broke. To set aside a default, the company also had to show a defense on the merits and that it acted diligently once it learned of the judgment, and it did both.

Compare a firm that chose its failure. In Emerald Coast Utilities Authority v. Bear Marcus Pointe, LLC (opens in a new tab), a law firm’s e-mail server deleted suspected spam permanently without telling anyone, a setting its IT consultant had warned against. The firm kept no logs and declined to pay for a filtering service. When the clerk e-mailed an appealable fee order, the firm said it never saw it, and no one there had checked the online docket, though everyone knew the order was coming. The First District held that the trial court could treat the setup as “a conscious decision to use a defective email system,” which cannot be excusable neglect. The time to appeal was gone.

In other words, the question is whether there was a working system for the mistake to slip through. A court gives a slip inside such a system the benefit of human error, though it looks harder when the lawyer, and not the staff, made the mistake. A system that was missing or knowingly left broken is the firm’s own choice, and its client bears the cost.

What no court can reopen

Excusable neglect is a way out of a judgment or an order. Some deadlines are set by statute, or mark the limit of a court’s power, and no finding about the lawyer’s conduct moves them.

The time to appeal is one. The thirty days to file a notice of appeal are jurisdictional, and Rule 1.090(b) forbids a trial court to extend them. That is why Dresdner ended where it did. Florida courts have granted relief when the court or the clerk caused the lateness, such as a judgment that was never mailed to the parties. A mistake inside the lawyer’s own office does not qualify, however excusable it is.

A statute of limitations is another. A negligence claim that accrued in Florida after March 24, 2023, must be brought within two years. A last day on a weekend moves to the next court day, as Herrero held, but a motion for relief from a judgment cannot revive a claim that was filed too late.

A case management order sits between the two. Its deadlines can move, but only by court order. Rule 1.200 says they “must be strictly enforced unless changed by court order.” A party that needs more time has to ask, saying why and when it learned it would need it.

What the court cannot reopen, the client still loses, and the loss becomes a claim against the firm. Legal malpractice has its own two-year limitations period, counted from when the client discovers the claim or should have. When the mistake came in a lawsuit that went to judgment, the Supreme Court of Florida held in Silvestrone v. Edell (opens in a new tab) that the clock starts when that judgment becomes final.

A calendar that checks itself

If courts forgive the slip and not the missing system, the system has to be the kind that catches its own slips. The cases describe what that takes. Emerald Coast said counsel must have “sufficient procedures and protocols in place,” including a spam filter with safeguards and an independent look at the court’s docket. Opposing counsel in that case had a paralegal check the docket every three weeks. In Hanniford v. United Services Automobile Ass’n (2025), the First District added that “every three weeks is likely too infrequent.” That firm had not updated its e-service designations as its lawyers changed. If it had, the court wrote, and “checked the docket as a backup, none of this would have happened.”

That is the design behind docket control. Every deadline lives in two calendars that do not depend on each other, kept by different people and entered from the source document each time. Ticklers warn the lawyer weeks ahead, while there is still time to act. The two calendars are compared on a schedule, and both are compared with the court’s docket. A typo in one calendar then shows up as a disagreement with the other. A rule the software got wrong shows up the same way, and so does an order that never arrived by e-mail.

Back to Sorrelwood

In the activity, Temko Eden has just been hired to defend Sorrelwood Freight Lines, and every deadline in the case is yours to find. Read the file in Part 1, then count each deadline by hand in Part 2, first day and last day, under the rule of the court that set it. Then run the Deadline Calculator and see where an AI’s count parts from yours.
