Massachusetts Civil Procedure Deadline Calculator

Computed under Mass. R. Civ. P. 6 · 33 deadlines across 8 categories

Pick a deadline, enter the trigger date, and this tool applies Massachusetts's own time-computation rule — including its short-period weekend/holiday exclusion, its 3-day mail/electronic-service add-on, and the Commonwealth's own legal-holiday calendar — and shows its work, step by step, with the governing rule cited.

Advanced: Suffolk County holidays & local court closures

Case is venued in Suffolk County (Boston) — also exclude Evacuation Day (Mar. 17) and Bunker Hill Day (June 17)

These two dates are legal holidays under G.L. c. 4, § 7 only in Suffolk County, though the same statute requires Suffolk County state and municipal offices to stay open and staffed on them. They still count as legal holidays for Rule 6(a) time computation in Suffolk-venued cases; check this box only if your case is venued there.

Additional non-business days (court closures, emergencies)

Comma-separated YYYY-MM-DD dates. This tool hard-codes only the 12 statewide G.L. c. 4, § 7 holidays; add any weather closure or other emergency non-business day here.
