Add India Central Government Working Days

Adds or subtracts dates using the pinned 2026 central-government Gazetted schedule and weekend baseline; Restricted and local optional selections are not inferred.

When to use

You need a deterministic central-government date offset with a required office scope.

Do not use when: You need an exact state/UT, bank, employer, school, exchange or locally selected optional-holiday calendar.

Example user requests

Add five Delhi central-government working days after 2026-10-16.

Formula

move one day at a time; decrement remaining only when selected status.is_working_day=true

Skip weekly rest days and applicable Gazetted dates; preserve Restricted options without treating them as closures.
