Nowruz is a festival which marks the new year according to the solar calendar.
It's celebrated in many countries in the Middle East and Central Asia, and across the world.
The word 'nowruz' comes from the Persian language and means 'new day'. Traditions include cleaning your home, making special foods, and preparing seven symbolic things known as the 'Haft Seen'. These all begin with the letter 'S' (or letter 'Seen' in Persian).
