The Thor'sday Thursday Festival is the biggest event of the year. EVERYBODY who is ANYBODY will be there, all the Hairy Hooligans AND the Meatheads.

In How to Train Your Dragon, the holiday of Thors'day Thursday is mentioned. It is also spelled Thor'sday Thursday.


It is not stated when or why Thors'day Thursday started, though it might have some religious connection to the Norse God of thunder, Thor. It is also not clear if this is an annual event or more or less frequent.


The celebration takes place on the Isle of Berk along the island's eastern shore. Visitors and off-island participants set up camp along Black Heart Bay. Vendors and performers set up shop at the Long Beach.

The visitors set up camp in Black Heart Bay, which turned overnight from an empty desert of echoing seagulls into a bustling village of tents made out of sails too patched to be used at sea anymore.

By the next morning the Long Beach was packed with stalls and jugglers and fortune tellers.
