There is no time difference between Bangalore and Mumbai. Both cities use India Standard Time (IST, UTC+5:30). When it's 12:00 PM in Bangalore, it's also 12:00 PM in Mumbai.
India uses a single timezone across the entire country, so all major Indian cities are synchronized.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 6:00 PM) without any time conversion needed.
Bangalore and Mumbai are two of India's most important business centers. Mumbai is the financial capital with the stock exchange and major banks, while Bangalore is the technology capital. This is one of India's busiest flight routes, with hourly flights connecting the cities in about 1.5 hours.
