A date range is a specific period of time defined by a start date and an end date. It is commonly used in various contexts, such as scheduling events, analyzing data, or setting deadlines. For example, a date range might be from January 1, 2023 to January 31, 2023, indicating all the days within that month. Date ranges can be expressed in different formats, such as "MM/DD/YYYY" or "YYYY-MM-DD." They help organize information and make it easier to understand time-related data. In databases, date ranges are often used to filter records, allowing users to retrieve information relevant to a specific timeframe.
