In the lead-up to Diwali, celebrants will prepare by cleaning, renovating, and decorating their homes and workplaces with "diyas" (oil lamps) and "rangolis". During Diwali, people wear their finest clothes, illuminate the interior and exterior of their homes with "diyas" and "rangoli", perform worship ceremonies of Lakshmi, the goddess of prosperity and wealth, light fireworks, and partake in family feasts, where "mithai" (sweets) and gifts are shared. Diwali is also a major cultural event for the Hindu, Sikh and Jain diaspora.
