Mumbai is always 1.5 hours ahead of Dubai. When it's 9:00 AM in Dubai, it's 10:30 AM in Mumbai. Neither city observes DST, so this difference is constant year-round.
Dubai uses GST (UTC+4) and Mumbai uses IST (UTC+5:30), creating the 1.5-hour gap with India's unique half-hour offset.
Business hours align excellently! 9:00 AM - 6:00 PM Dubai corresponds to 10:30 AM - 7:30 PM Mumbai. Nearly complete working day overlap.
Mumbai and Dubai have extremely close ties - Dubai has the largest Indian expat community in the world. Emirates and Air India operate 20+ daily flights on this busy route.
