The ideal time for a company opening is a weekday afternoon. Preferably plan Tuesday to Thursday, between 3 p.m. and 6 p.m. That fits working hours and makes press coverage more likely. In terms of duration, an opening of two to three hours works best. In that time you can fit a short speech, a ceremonial act such as a ribbon-cutting, a tour and a networking get-together. Take the season into account: spring and autumn are popular, summer often empties out due to holidays. Plan at least six to eight weeks ahead. That gives press, partners and staff the chance to free up their diaries. Live Impact advises on timing based on your audience and objective.
