definition"time span over one or more calendar days"
note"A date period is considered unknown or incomplete if either the start date or the end date has no value. There may be cases, however, when the length of time is known, such as a 4-day work week, but the precise start and end of that week are not known."
note"A date period is typically defined by at least two of three properties: (1) a start date, (2) an end date, and (3) a duration. If more than one of these properties is missing, the date period may be invalid, incomplete, or unknown."
