Opening ceremony
An opening ceremony, grand opening, or ribbon-cutting ceremony marks the official opening of a newly-constructed location or the start of an event. Opening ceremonies at large events such as the Olympic Games, FIFA World Cup, and the Rugby World Cup might involve thousands of participants and be watched worldwide.
In the case of physical establishments, its grand opening might be preceded by a "soft opening" or "soft launch" in which the establishment begins to operate with little promotion, to allow testing of operations, procedures, and facilities.
