Pair comparison

India vs Japan

India is 3.5 hours behind Japan. Their business-hour overlap is 5.5 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

Coordination class

moderate handoff pair

India and Japan have a usable but finite overlap window. Cluster live decisions inside that window and push reviews, approvals, and status updates async.

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 17 listed holidays

India and Japan have different public-holiday calendars, but neither side dominates the year by count in this dataset. Check local observances before firm launch dates.

Pair workflow examples

What fixed local work times become across the pair

moderate handoff pair

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.
