When is Independence Day?
In 2026, Independence Day falls on Thursday, September 24, 2026. It is classified here as a paid public holiday.
History of Independence Day
On September 23–24, 1973, the first National People’s Assembly met at Boé in PAIGC-controlled territory and proclaimed the State of Guinea-Bissau on September 24. The declaration followed a decade of armed struggle and institution-building and occurred months after Cabral’s assassination, before Portuguese colonial authority accepted it.
Portugal recognised Guinea-Bissau on September 10, 1974 after the Carnation Revolution, and the country joined the United Nations on September 17. September 24 centres the assembly’s own act of sovereignty rather than later recognition. Celebration can honour liberation while allowing critical discussion of war, one-party rule and post-colonial state-building.
Independence Day is one of the eight mandatory national holidays in Decree 1/2023. Article 1 orders work to stop in public and private sectors except activities that cannot be interrupted. Labour Code articles 142 and 161 preserve remuneration; an employee working for an establishment lawfully kept open receives equal compensatory rest or a 100% pay supplement, at the employer’s choice. Monday observance requires special legislation under article 141(3), so weekend substitution is not automatic.
How Independence Day is observed
Mandatory national holiday on Thursday, September 24, 2026. No special Friday substitute or bridge followed automatically. Current government notices, employer policies and local schedules in Guinea-Bissau should be checked for closures, substitute dates and public-service arrangements.
Traditions of Independence Day
Community practice
Households may display the flag, follow broadcasts, attend community events or remember relatives connected with liberation. National and local institutions may hold flag-raising events, commemorations or official addresses connected with the history behind the holiday.
Public or religious programme
State and regional programmes may include military honours, speeches, wreaths, music, dance and recognition of veterans. Schools, museums and broadcasters often revisit the people and events associated with the date, adding context to the public celebration.
Planning the date
Work normally stops apart from uninterrupted activities. Check parade routes, security controls and September 25 opening hours. Concerts, parades, memorial visits or family gatherings allow communities to mark the occasion beyond the formal state programme.
Dates and observance rules are checked against the official Guinea-Bissau official holiday calendar or legislation. Government, regional, school and employer schedules in Guinea-Bissau may differ; check the linked official source and current local notices before making time-sensitive plans.
