And for my foreign readers, you may get an idea with this:
Diwali is an official holiday in India, Nepal, Sri Lanka, Myanmar, Mauritius, Guyana, Trinidad & Tobago, Suriname, Malaysia, Singapore, and Fiji.
The name “Diwali” is a contraction of “Dipawali” (Sanskrit: दीपावली Dīpāwalī), which translates into “row of lamps”. Diwali involves the lighting of small clay lamps (diyas or dīpas) in Sanskrit: दीप) filled with oil to signify the triumph of good over evil. During Diwali, all the celebrants wear new clothes and share sweets and snacks with family members and friends.
The festival starts with Dhanteras on which most Indian business communities begin their financial year. The second day of the festival, Naraka Chaturdasi, marks the vanquishing of the demon Naraka by Lord Krishna and his wife Satyabhama. Amavasya, the third day of Diwali, marks the worship of Lakshmi, the goddess of wealth in her most benevolent mood, fulfilling the wishes of her devotees. Amavasya also tells the story of Lord Vishnu, who in his dwarf incarnation vanquished the Bali, and banished him to Patala. It is on the fourth day of Diwali, Kartika Shudda Padyami, that Bali went to patala and took the reins of his new kingdom in there. The fifth day is referred to as Yama Dvitiya (also called Bhai Dooj), and on this day sisters invite their brothers to their homes.” From wikipedia.
I’m going to get ready in such loud clothing today!
