The term "arrival date" refers to the specific day or time when an individual, group or object is expected to arrive at a particular location. This could be in reference to someone traveling to a new city for work or vacation, a shipment of goods being delivered to a business, or even an event such as a concert or conference that has a scheduled start time and date. The arrival date serves as the point of reference for planning and preparations leading up to the event, ensuring everything is in order beforehand.
