Legal Definition
A business day refers to a day on which normal commercial or legal activities are conducted, typically excluding holidays or non-working days. In a legal context, it defines the operational period for transactions, deadlines, and proceedings.
Plain-English Translation
It means a day when people usually go to work or do business. For example, if Monday is a business day, then Tuesday is also a business day, but if there's a holiday (like Thanksgiving), that might not be a business day.
