Singapore is exactly 2.5 hours ahead of Mumbai year-round. When it's 3:00 PM in Singapore, it's 12:30 PM in Mumbai. India uses UTC+5:30 and Singapore uses UTC+8, creating a constant 2.5-hour difference.
Neither Singapore nor India observes daylight saving time, so this difference remains constant throughout the year.
Optimal meeting window: 10:30 AM - 5:30 PM Singapore time (8:00 AM - 3:00 PM Mumbai). Great overlap for full business day coordination.
Singapore has one of the largest Indian diaspora communities in the world, and many Indian tech companies have regional headquarters in Singapore.
