On St David's Day schools up and down the country will be ditching maths, geography and chemistry for a day of competition in music, poetry and art.
We call it an Eisteddfod (ice-teth-vod).
A celebration of creativity traced back to 1176 AD when Lord Rhys invited musicians and poets to compete for a seat at his table.
We love old traditions, and making new ones.
One of the categories at this years children's Eisteddfod is 'Create a Website'.
Creativity has changed a lot in 831 years.
To the right you'll find a few things to help your children join in the celebrations.
