Supersunnuntai is a Finnish festival brand focused on bringing families together for a shared event experience. Described as Finland’s largest festival for the whole family, it takes place in multiple cities, giving visitors around the country the opportunity to attend. In summer 2026, Supersunnuntai was held in Helsinki, Seinäjoki, Tampere and Espoo, with event schedules and news published for visitors ahead of the celebrations.

The brand’s central offering is its family festival, supported by ticket information and event updates through its website. Supersunnuntai also invites attendees to share feedback through a visitor survey, helping inform the development of future events. The survey is conducted by Sponsor Insight Finland on behalf of the event organiser, and responses are handled anonymously and confidentially. Participants could enter a draw for a 100-euro Tiketti gift card.

The website provides dedicated information for media and contact enquiries, along with a newsletter subscription option. Supersunnuntai presents itself as a nationwide event experience, combining festival attendance, practical visitor information and opportunities to help shape the event’s future.
