The California State Assembly adopted a resolution recognising November 8 as Diwali Day and urged citizens of the state to take part in the celebration. The resolution, moved by assembly members Darshana Patel and Ash Kalra, also expresses deepest respect for Indian Americans and the Indian diaspora in California and throughout the world on this prominent occasion. "...the Assembly recognizes this year's Diwali festival on Sunday, November 8, 2026, and encourages Californians to take part in this joyous day of celebration," said the resolution, adopted by the assembly on Thursday.

It said that Diwali, a festival of great significance to Indian Americans and South Asian Americans, is celebrated annually by Hindus, Sikhs, Buddhists, and Jains throughout the United States, and across the globe. Diwali or Deepavali, which means "a row of lamps," is one of the world's oldest holidays that brings families, friends, and communities together for a celebration of generosity, unity, joy, appreciation, and a time of reflection, the resolution said.
