Enjoy chilling out on the sofa on Saturday, 23 June because, to celebrate Cyw's 10th birthday, S4C will be showing nothing but Cyw programmes, old and new, all day long – from 6.00 in the morning until 6.00 in the evening!

Tref a Tryst return for a one-off special at 8.00 in the morning. Get involved by playing the Bowowownsio game, and be in with a chance of winning some fantastic prizes including a family holiday at one of the Urdd centres! The dynamic duo will be joined by some very special friends, including Ben Dant, Tara Tan Toc and Cyw presenter, Huw!

Get the popcorn ready for a movie marathon! We'll have not one, but two brand new Paw Patrol films, along with a special Fireman Sam film – 'The Great Fire of Pontypandy'. And enjoy some of the classics too, including Y Raplyfr Coll, Ble mae Cyw? and Dona Direidi – Be Wnei Di?

We'll also be finding out the Top 10 favourite Cyw programme of all time, as voted by you.
