Court-Martial Deadline Calculator

Enter the case dates you know. The calculator returns every deadline, waiting period, and effective-date rule those dates trigger under the Rules for Courts-Martial, the Military Rules of Evidence, and the UCMJ — in one chronological calendar, each linked to the governing provision. New to the sequence these dates sit in? Start with the court-martial process overview.

Verify every date before you rely on it

These dates are calendar arithmetic applied to the periods stated in the rules. They are a starting point for your own computation — not a determination of any deadline in your case. Before acting on any date here, check it against:

the text of the rule or article itself — follow the citation link on each row and read it;
the Military Judges’ Benchbook (EBB) instruction, where one applies;
current case law — appellate decisions construe how these periods run, what tolls or excludes them, and how they are computed; and
your service’s implementing regulations, which may impose shorter or additional deadlines.

The calculator does not account for excludable delay, tolling, weekends and holidays, service-specific rules, or any order of the military judge — each of which can move a real deadline. Not legal advice.

WHAT THIS COVERS

Every provision of the Rules for Courts-Martial, the Military Rules of Evidence, and the UCMJ (10 U.S.C. ch. 47) that ties a specific number of days — or, for pretrial confinement and interlocutory appeals, hours — to an event: a deadline to act, a minimum waiting period, an effective-date rule, a speedy-trial restart, a maximum punishment expressed in days, or an offense-severity threshold.

Only clock-driven entries are turned into dates. Maximum punishments, severity thresholds, and credit ratios (Article 15’s limits, the Article 86 absence table, the R.C.M. 305(l) confinement credit) are carried in the full reference chart but are never computed as deadlines — they are not dates.

Where a period appears only in a non-binding Discussion, the entry is badged as such. Where the same deadline appears in both the statute and the implementing rule — the Article 35 / R.C.M. 602 waiting period, the Article 57 / R.C.M. 1102 effective date, the Article 66/67/69 / R.C.M. 1201/1203 appeal deadlines — both are listed, because they are formally separate provisions.

Not legal advice. This calculator is an informational aid. It applies ordinary calendar arithmetic to periods stated in the Manual for Courts-Martial and the UCMJ; it does not account for excludable delay, tolling, the treatment of weekends and holidays, orders of the military judge, or the facts of any case. Verify every date against the rule or article itself, the Military Judges’ Benchbook instruction where one applies, current case law, and your service’s implementing regulations — any of which may change how a period is computed or impose a deadline this tool does not carry. Consult a judge advocate or qualified counsel before relying on any date shown here.
