Bali is 2.5 hours ahead of India (UTC+8 against IST). A direct overnight flight from Mumbai or Bengaluru lands you in Denpasar in the morning, so book your airport transfer for arrival rather than assuming an afternoon check-in.
Vegetarian and Jain food is easy in Ubud, Seminyak and Canggu, and there are established Indian restaurants across the south, but ask specifically about shrimp paste (terasi) and fish sauce in Balinese dishes — they appear in food that otherwise looks vegetarian.
Bali is Hindu-majority, and temple etiquette matters: a sarong and sash are required, and menstruating women are traditionally asked not to enter temple courtyards. Alcohol is expensive by Indian standards, while spa treatments, drivers and villas are noticeably cheaper.
Peak Indian demand falls in the May-June school break and around Diwali and the year-end holidays, which is exactly when fares and villa rates spike. April, September and early October are the best value windows with reliable dry-season weather.
