Coordination class
moderate handoff pair
Spain and Argentina have a usable but finite overlap window. Cluster live decisions inside that window and push reviews, approvals, and status updates async.
Pair comparison
Spain vs Argentina
Spain is 4.0 hours ahead of Argentina. Their business-hour overlap is 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.
