What is Open House?

An open house is a type of party where hosts specify a window of time (such as 2-6 PM) during which guests can drop in at their convenience. Unlike traditional parties where all guests arrive at a set time, open houses allow flexibility for attendees to come when it suits their schedule. This format is popular for graduation parties, holiday gatherings, housewarming events, and celebrations expecting large numbers of guests. The casual nature means lighter food (appetizers or finger foods that remain available throughout), and the atmosphere is relaxed and conversational.
