Coordination class
easy business overlap
India and Singapore have a broad overlap window today, so normal recurring meetings are low-friction. Still recheck invites around DST transition weeks.
Pair comparison
India vs Singapore
India is 2.5 hours behind Singapore. Their business-hour overlap is 6.5 hours per day.
Country comparisons use one representative IANA zone per country, current public-holiday rows, and a same-day business-hour model. Multi-zone countries still need city-level checks before travel or payroll decisions.

Operational read on this pair
DST drift risk
0 sampled shifts / 12mo
Neither sampled reference zone has a DST transition in the next 12 months, so the offset gap is unusually stable for recurring calls.
Holiday availability
16 vs 10 listed holidays
India and Singapore share 4 listed holiday dates in the selected year, so shared shutdown risk is visible before campaign or sprint planning.
Pair workflow examples
What fixed local work times become across the pair
