close of business
Office hours finish
Close of business refers to the end of a standard workday, typically around 5 or 6 p.m. in office settings.
It establishes a deadline for transactions, communications, or deliverables: I need that report by close of business Friday.
Often abbreviated COB or EOD (end of day), the phrase is common in corporate and legal contexts where precise timing matters.
In global business, close of business may require specifying a time zone.
