The slowest month for jury duty is December, when holiday closures, judicial conferences, and widespread attorney vacations shrink the trial calendar and, with it, the number of jurors courts need to summon. July and August form a secondary lull for similar reasons. No national database publishes month-by-month summons totals, so the pattern comes from the observable mechanics of how courts schedule trials.
Why December Is the Quietest Month
Court closures pile up fast in December. Between Christmas Eve, Christmas Day, New Year’s Eve, and the proximity of Thanksgiving in late November, federal and state courts lose a significant chunk of working days. Starting a multi-week trial in early December means risking interruptions from holidays, juror travel, and attorney unavailability. Most judges simply avoid it. Fewer trials get scheduled, so fewer summonses go out.
Judicial conferences also tend to cluster in late fall and early winter. When judges attend these professional development sessions, their courtrooms go dark. Trial attorneys often take planned leave during the same stretch, making it difficult to assemble the full cast a trial requires. Court administrative staff use the slowdown to clear filing backlogs, update case management systems, and handle year-end reporting. All of this shrinks demand for jurors.
The Summer Slowdown
July and August follow a similar pattern, though less pronounced. Vacation schedules for judges, attorneys, and court reporters reduce the number of courtrooms running at full capacity. A trial that requires consistent daily attendance from a specific judge and legal team is hard to manage when key players are cycling in and out of leave for weeks. Many courts respond by scheduling fewer jury trials during this window and focusing on pre-trial hearings, motions, and settlement conferences that do not require a jury.
When Courts Are Busiest
September through November and January through May tend to be the heaviest stretches for jury summonses. Courts emerging from a slow period often have a backlog of cases ready for trial, so demand for jurors can spike. A summons that arrives in September or January is not a coincidence of timing.
How Summons Numbers Actually Get Set
Court administrators do not pull jury numbers out of thin air. Each federal district court maintains a written plan for randomly selecting jurors from voter registration lists and other sources, aiming for a fair cross-section of the community.1Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection The administrator reviews the master trial calendar, counts how many cases are marked ready for trial, and estimates how many jurors will be needed for selection panels. If a wave of plea deals or settlements hits before the trial date, the court scales back and may cancel reporting dates for some summoned jurors.
This is where the seasonal pattern becomes mechanical. A December calendar with four trials produces far fewer summonses than a March calendar with twenty. Administrators also weigh cost. Federal jurors receive $50 per day just for showing up, so summoning hundreds of people who never see the inside of a courtroom wastes real money.2Office of the Law Revision Counsel. 28 USC 1871 – Fees That pressure gives every clerk an incentive to match the pool tightly to actual need.
Federal and Local Courts Follow Different Rhythms
Federal courts and state or municipal courts operate on different calendars, and the slow periods do not always overlap. Federal courts follow the Federal Rules of Civil and Criminal Procedure, and their caseloads skew toward different types of matters than a county courthouse handling traffic offenses, divorces, and landlord-tenant disputes. A local court might stay busy in December processing short misdemeanor trials while the federal courthouse across the street has gone quiet.
Many state courts also operate under “terms of court,” set periods when the court is officially in session for trials. Some rural jurisdictions hold jury trials only during specific weeks scattered throughout the year, meaning their slow periods have nothing to do with national holiday patterns and everything to do with local scheduling tradition. The only reliable way to learn your specific court’s rhythm is to check the local court calendar or call the clerk’s office.
Grand Juries Don’t Follow This Pattern
The seasonal pattern applies to trial (petit) juries. Grand juries work on a different cycle. A federal grand jury can serve for up to 18 months, with a possible six-month extension if a court finds it necessary.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Because grand jurors serve on a recurring schedule over many months rather than reporting for a single trial, their summons timing has little connection to the busy or slow trial season. Grand jury terms often begin at fixed points in the year regardless of holiday schedules.
How Much the Slow Month Really Matters to You
Most courts now use a one-day, one-trial system. You fulfill your service obligation either by sitting through one trial or by being available for one day without being selected. If you report and no trial needs you, your duty is done. Even in the busiest months, an individual juror’s actual time commitment stays short unless assigned to a lengthy trial. The upshot: being summoned in March versus December changes the odds you’ll be called at all, but not much about what happens if you are.
If Your Summons Arrives at a Bad Time
Getting summoned during an inconvenient month does not mean you are stuck with that date. Federal courts allow temporary deferrals on grounds of undue hardship or extreme inconvenience, and each of the 94 federal district courts sets its own policies for handling these requests.4United States Courts. Juror Qualifications, Exemptions and Excuses State courts generally offer similar options. Common reasons courts accept include business conflicts, health issues, pre-booked travel, and active enrollment as a student.
Most courts allow one postponement as a matter of course, typically requiring you to specify a future date when you are available. If you want to steer toward the quiet part of the calendar, you can propose a December or late-summer week when requesting a new date. Respond promptly through the number on your summons or the court’s online portal, well before your reporting date. Courts are usually reasonable about rescheduling, but they have no patience for people who simply do not show up.
