About Constitution Day

Constitution Day in Seychelles is observed on June 18 and is listed by the government as a public holiday.

The date commemorates the 1993 approval and adoption of the Constitution of the Third Republic following a national referendum.

Why Constitution Day matters

The observance marks a constitutional milestone in Seychelles and provides a civic occasion for learning about the country’s constitutional framework, institutions, rights and responsibilities.

A factual guide can describe the constitutional history and official ceremonies without endorsing a political party, officeholder or interpretation of contemporary politics.

History of Constitution Day

Seychelles government history records that the new constitution was approved by voters on June 18, 1993, following the constitutional process for the Third Republic.

For many years June 18 was also Seychelles’ National Day. In 2014 the government announced that National Day would move to June 29, the anniversary of independence, beginning in 2015.

June 18 continued as Constitution Day, and official State House material from June 2015 onward uses that name. Current government calendars list Constitution Day on June 18 as a public holiday.
