Multiday

Multiday describes events, activities, or phenomena that extend over more than one calendar day. It is often used to distinguish between events that last a day or less and those that involve multiple days, sometimes including overnight periods. The term is commonly applied to events such as festivals, conferences, competitions, expeditions, and vacations.

In travel and tourism, multiday itineraries allow visitors to spend several days in a destination, often featuring lodging, meals, and guided activities. In entertainment and culture, multiday festivals and concerts unfold over consecutive days, requiring planning around schedules, accommodations, and crowds. In sports, multiday competitions include stage races, tournaments, and multi-day matches, typically spread across several calendar days.

Planning considerations include ticketing options, transportation, lodging, meals, weather, safety, and contingencies for delays or changes in plan. Organizers may publish schedules, evacuation routes, and accessibility information to accommodate participants and attendees across multiple days.

In data and software, multiday also describes time spans in logs or datasets where events occur over several days. Calendar and scheduling tools use multiday markers to display events that span across midnight or several dates.
