It takes place in Lerwick, Shetland, on the last Tuesday in January every year. Up Helly Aa day involves a series of marches and visitations, culminating in a torch-lit procession and the burning of a galley. This is followed by hours of performing acts and dancing in halls throughout Lerwick. There is a main guizer who is dubbed the "Jarl". There is a committee which a person must be part of for 15 years before one can be a jarl, and only one person is elected to this committee each year. The procession culminates in the torches being thrown into a replica Viking longship or galley.
