Use this when you need a deterministic 2026 central-government office baseline and can specify Delhi/New Delhi versus outside Delhi. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need a state, Union Territory, bank, employer, school, exchange, or an outside-Delhi locally selected optional-holiday calendar. What it computes: Checks a 2026 date against the Department of Personnel and Training central-government holiday schedule, preserving Gazetted and Restricted distinctions. Example user requests: Is 2026-10-20 a working day for India's central government office in Delhi? | Is 2026-08-28 a guaranteed closure or only a restricted holiday option outside Delhi? Inputs: date (date); office_scope (enum). Complete JSON argument examples: {"date":"2026-10-20","office_scope":"delhi_new_delhi"} | {"date":"2026-08-28","office_scope":"outside_delhi"} Outputs: territory, territory_name, office_scope, office_scope_name, weekday, is_working_day, is_guaranteed_non_working_day, day_type, gazetted_holiday_names, restricted_holiday_names, restricted_holiday_available, calendar_scope, rest_day_policy, restricted_holiday_policy, selection_policy, substitute_day_policy, calendar_profile, dataset_version, sources.
