Pair comparison
United States is same time as Canada. Their business-hour overlap is 9 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.

DST drift risk
4 sampled shifts / 12mo
Both sampled reference zones shift clocks. The offset gap can still move temporarily when the countries change on different weekends.
Holiday availability
16 vs 31 listed holidays
United States and Canada share 11 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
9 shared business hours is enough for normal recurring meetings, reviews, and same-day escalation, assuming neither side is on holiday.
