Phoenix is 12.5 hours behind Mumbai year-round. When it's 10:30 PM in Mumbai, it's 10:00 AM the same day in Phoenix. India uses UTC+5:30, creating the half-hour offset. Neither Phoenix nor India observes daylight saving time.
Arizona (except the Navajo Nation) does not observe daylight saving time, making Phoenix one of the easiest US cities for scheduling calls with India.
Optimal meeting window: 6:00 AM - 8:00 AM Phoenix time (6:30 PM - 8:30 PM Mumbai). Early morning Phoenix catches evening Mumbai.
Phoenix has a growing Indian-American community and the city's tech sector has increasing ties to India's IT industry.
