Today, 20 March 2021 is Nowruz, the Iranian New Year. This ancient tradition has been celebrated for over 3000 years.
It is said that Persian king Jamsid saved the world from a winter that threatened to kill everything and everyone. He had a throne made from gems, and had demons raise him into the sky where he shone like the sun.
People from Iran and Central Asia often have a table in their house with various items (similar to the picture) symbolising the new year, growth and prosperity. There are various other new year customs, which you can read about here.
