# Shift explicit business dates

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Shift date-only Gregorian values by working days under supplied weekly closures and explicit closed dates. Roll an initially closed anchor explicitly, then count open dates strictly after or before it. No holiday lookup, clock, timezone or legal deadline verification.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Add or subtract business days on an explicit supplied closure calendar
- Roll a closed starting date before a date-only working-day offset

## Outside this profile
- National holiday discovery, bank settlement or legal deadline advice
- Working-hour arithmetic, timezone conversion, recurring event scheduling or real organization calendar verification
- Live execution, network lookups, payments, reservation, or inferring factual correctness of supplied data

Proposed nominal USD 0.003 per successful call; payer fees excluded. No verified runtime availability.
