The feast of Corpus Christi is a Christian observance celebrating the Eucharist — also known as Holy Communion. The feast, the date for which changes often, is celebrated mainly by Roman Catholics and it falls on the first Thursday in most countries or first Sunday in the U.S. after Trinity Sunday — 60 days after Easter.

The name "Corpus Christi" is of Latin origin meaning the body of Christ. The day commemorates the Last Supper before Jesus Christ was believed to have been crucified.

Feast of Corpus Christi is a public holiday in countries such as Austria, Bolivia, Brazil, Croatia, Dominican Republic, Poland, Portugal, and Trinidad and Tobago. However, the day is not an official holiday in countries like Australia, Canada, the United Kingdom and the U.S.

The day is celebrated with processions led by high-ranking clergy. A mile-long carpet is made out of flower petals, on which the procession is carried on. In villages, streets and doorways are decorated with flowers and leaves. While, in recent years, the practice is no longer common, some communities still follow the tradition.
