The calendar day also contrasts the working or business day, which excludes holidays of all sorts, but in some cultures may include one of the weekend days, e.g. Saturday, although it is not considered a weekday. Also, a calendar day always runs 24 hours (except for DST changes) from 00:00 through 24:00, whereas a business day may be constrained by work or opening hours and may span over midnight.
