The Solemnity of the Immaculate Conception is a Catholic feast celebrating Mary's conception without sin. The day is designated as a non-working Public holiday in honor of the Virgin Mary. Filipino Catholics have an especially strong devotion to Mary. The celebration of the Feast of the Immaculate Conception of Mary is preceded by nine days of Novena Masses, and the church is specially decorated for these Masses.

In the Philippines, there are only two kinds of holidays: regular holidays, and special non-working holidays.

Regular holidays are those that usually have a fixed date, such as New Year's Day, Independence Day, and Christmas Day.

Special Holidays, on the other hand, are more flexible. Apart from being enacted by Congress, they can also be declared by the President of the Philippines.
