The bill aims to officially designate Diwali, also known as Deepavali or the Festival of Lights, as a recognized holiday in the state of Michigan. It specifies that this holiday will be celebrated on the new moon day of the eighth lunar month according to the Indic primnta lunisolar calendar, acknowledging its significance to the Hindu, Jain, and Sikh communities.

The legislative language includes a declaration by the Michigan legislature that formalizes this recognition of Diwali as a holiday, thereby promoting cultural awareness and inclusivity within the state.
