enddate

EndDate is a concept used across scheduling, records management, and software systems to denote the termination point of a time-bound interval. It defines the latest moment or date at which a period, contract, eligibility window, or data retention rule remains in effect. In many contexts endDate is used together with startDate to form a closed interval [startDate, endDate], although some systems treat the endDate as exclusive or non-inclusive.

Formats and types: EndDate may be a date (YYYY-MM-DD), a date-time (YYYY-MM-DDTHH:MM:SS), or a timestamp with time zone (e.g., 2024-06-18T15:30:00Z). In databases and APIs, the field can be nullable to indicate a currently active item. When endDate is omitted, ongoing validity is implied; when present, it constrains operations such as filtering, reporting, and access control.

Practical considerations: Time zone consistency is important; convert dates to a common time zone for comparisons. The interpretation of endDate as inclusive or exclusive affects calculations and user expectations. A contract ending on 2024-12-31 could include that date if inclusive; otherwise it ends at the start of 2025-01-01. EndDate is often contrasted with startDate, duration, expiration date, renewal date, or lastUpdated. See also startDate and expirationDate.
