Long weekends in São Tomé & Príncipe, 2026
6 runs of three days or more, including the ones you only get by taking a single bridge day off. Computed on a Monday–Friday week. The corpus holds Sunday as this jurisdiction’s statutory weekly rest — verified — but a labour code names the day it guarantees, not the days custom adds, so it is cited above rather than computed from.
