All Saints’ Day

All Saints' Day, also known as All Hallows' Day, the Feast of All Saints, the Feast of All Hallows, the Solemnity of All Saints, and Hallowmas, is a
Christian solemnity celebrated in honour of all the saints of the church,
whether they are known or unknown. From the 4th century, feasts
commemorating all Christian martyrs were held in various places, on various
dates near Easter and Pentecost. In the 9th century, some churches in the
British Isles began holding the commemoration of all saints on 1 November,
and in the 9th century this was extended to the whole Catholic church by
Pope Gregory IV. In Western Christianity, it is still celebrated on 1
November by the Roman Catholic Church as well as many Protestant churches,
as the Lutheran, Anglican, and Methodist traditions. The Eastern Orthodox
Church and associated Eastern Catholic and Eastern Lutheran churches
celebrate it on the first Sunday after Pentecost.

Feast of the Immaculate Conception

The Solemnity of the Immaculate Conception, also called Immaculate Conception Day, celebrates the sinless lifespan and Immaculate Conception
of the Virgin Mary, celebrated on December 8, nine months before the feast
of the Nativity of Mary, celebrated on September 8. It is one of the most
important Marian feasts in the liturgical calendar of the Roman Catholic
Church celebrated worldwide. By Pontifical decree, it is the patronal feast
day of Argentina, Brazil, Italy, Korea, Nicaragua, Paraguay, the
Philippines, Spain, the United States, and Uruguay. By royal decree, it is
designated as the day honoring the patroness of Portugal. It is celebrated
by the Roman Catholic Church and some select Protestant Christian
denominations. Since 1953, the Pope visits the Column of the Immaculate
Conception in the Piazza di Spagna to offer expiatory prayers commemorating
the solemn event.
