calendar day
Single dated unit
A calendar day is the full 24-hour period from midnight to midnight, as marked on a calendar.
The term distinguishes complete days from partial days or working hours: The package will arrive within three calendar days.
Legal and business contexts use it to clarify deadlines that include weekends and holidays, unlike "business days."
