Best meeting windows
Standard 9 AM – 5 PM hours in Singapore and UTC do not overlap. Plan calls for early Singapore morning or late Singapore evening, and rotate the burden between sides.
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.
