Does it automatically know all holidays?

No, to remain globally deterministic and local, the agent must pass an array of specific holiday dates (e.g., local state holidays) to be skipped during the count.

Does it count the start date?

No. In accordance with most civil procedural rules (like the Brazilian CPC), the count begins on the first business day *after* the start date.

Is this secure for client data?

Absolutely. The engine executes locally within the Vinkius Edge runtime, meaning no deadline inquiries are sent to external APIs.

In the legal profession, missing a deadline is catastrophic. Language models notoriously fail at date math, completely ignoring weekends and national holidays when asked to add 15 business days. This engine performs exact, local procedural deadline computations. By natively processing ISO dates and explicitly skipping non-business days and user-provided holidays, it ensures your autonomous legal agents never miss a filing date.
