Best meeting windows
If both teams keep standard 9 AM – 5 PM hours, the overlap window is roughly 2:00 PM – 5:00 PM in Singapore time. That gives you 3 hours per workday for live meetings.
Tighter overlap is achievable by having the side with later working hours start earlier, or by treating the first and last hours of each side as flexible. The bar above marks every hour where both cities sit inside a 9 AM – 5 PM window.
