The Great Orchestra of Christmas Charity (GOCC, Polish Wielka Orkiestra Świątecznej Pomocy, WOŚP) is the biggest, non-governmental, non-profit, charity organization in Poland.
The foundation supports paediatric and geriatric wards and operates since 1993.
The Grand Finale fundraiser takes place on the second Sunday in January. The day-long public fundraiser is held in Poland and everywhere where there is an active Polish community.
The public fundraiser is organised locally, by volunteer-run Collection Centres, and is accompanied by various events such as concerts, sporting competitions, and firework displays. A telethon, broadcast nationally, is held on the day as well.
Volunteers, carrying branded collection boxes collect money across the country, and people donating money receive distinct red-heart stickers in return.
