Diwali, which is also called the Festival of Lights or Deepavali, is a joyful five-day festival celebrated by millions  across the globe. The main idea behind Diwali is good triumphing over evil, and light conquering darkness. That’s why another part of the Diwali celebration involves people bringing light into their lives with fireworks, candles, and lanterns. People also celebrate by bringing color into their homes by creating intricate patterns called rangolis from colored powder, rice, and flowers.
