Step-by-step explanation:
When listing the hours of operation for a new agency, you should deal with holiday closings by detailing the hours of Regular business days and Federal holidays.
Regular business days refer to the normal working days of the agency, such as Monday to Friday. You would specify the exact hours the agency is open on these days.
Federal holidays are specific dates recognized by the government as public holidays. On these holidays, the agency may be closed or have modified hours, so it's important to include this information in the hours of operation.
