Diwali Explained: What It Marks and How India Celebrates
Diwali is the largest festival in India, observed across religions and regions with different stories behind the same idea: light over darkness.
The five days
- Dhanteras - buying metal, utensils or gold is considered auspicious and markets stay open late.
- Naraka Chaturdashi - the early morning oil bath, especially in the south.
- Lakshmi Puja - the main night. Homes are lit with diyas and the goddess of prosperity is invited in.
- Govardhan Puja or Bali Pratipada - regional observances, often the start of a new business year.
- Bhai Dooj - siblings celebrate each other.
Regional differences
In north India, Diwali is tied to the return of Rama to Ayodhya. In Bengal the same night is Kali Puja. In Tamil Nadu, Deepavali falls a day earlier and centres on the dawn ritual. Jain communities mark the liberation of Mahavira, and Sikhs observe Bandi Chhor Divas.
What it looks like on the ground
Expect strings of lights on every street, rangoli at doorways, an enormous volume of sweets exchanged between neighbours, and fireworks. Several cities now restrict fireworks to fixed hours or green crackers because of air quality, and Delhi air is typically at its worst in the days after.
If you are travelling during Diwali
- Book trains and flights at least a month ahead; this is the peak domestic travel week.
- Expect closed shops and offices for two to three days.
- Accept sweets when offered. Taking a box when visiting a home is standard courtesy.
- If air quality matters to you medically, consider spending that week on the coast or in the south.
Diwali is the best week to see Indian domestic life up close, provided the logistics are locked in early.
