Dubai is exactly 1.5 hours behind Mumbai year-round. When it's 3:00 PM in Mumbai, it's 1:30 PM in Dubai. India uses UTC+5:30 and Dubai uses UTC+4, creating a constant 1.5-hour difference.
Neither Dubai nor India observes daylight saving time, so this difference remains constant throughout the year.
Any business hours work great! With only a 1.5-hour difference, 9:00 AM - 6:00 PM Dubai corresponds to 10:30 AM - 7:30 PM Mumbai. Excellent overlap for business.
Dubai has one of the largest Indian expatriate populations in the world, and Mumbai-Dubai is one of the busiest international air routes globally with dozens of daily flights.
