Pair comparison
India is 2.5 hours behind Singapore. Their business-hour overlap is 6.5 hours per day.
Last updated recently. 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.

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.
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
The current offset is enough for today, but the examples below make the page useful for real recurring work: standups, reviews, and end-of-day handoffs anchored to either country. Recheck these around DST transition weeks when either sampled zone shifts.
Best live-use strategy
6.5 shared business hours is enough for normal recurring meetings, reviews, and same-day escalation, assuming neither side is on holiday.
