A "Business Day" typically refers to any day when normal business operations are conducted. This usually excludes weekends and public holidays, meaning it generally falls between Monday and Friday. Financial institutions and businesses use this term to determine deadlines for transactions, deliveries, and other operational activities. In many countries, a Business Day is defined as a period from 9 AM to 5 PM, although this can vary by industry. For example, banks may have different hours, and stock markets operate during specific times. Understanding Business Days is essential for planning and scheduling in the corporate world.
