Where 180 days shows up
Just under six months, 5.914 by the average, which puts 180 days about two and a half days short of a real half-year. The gap is worth knowing wherever the six-month figure is the rule: many countries require a passport valid at least six months beyond the intended date of departure, and counting 180 days forward instead of six calendar months leaves you a couple of days inside that margin. Six consecutive months run 181 to 184 days depending on where in the year they fall.
