A feast day is that date assigned by the Church when each particular saint is memorialized at Mass. Keep in mind that there are more than 10,000 named saints and only 365 days each year. That means on any given day a number of saints share the date. Sometimes the date corresponds to the date the saint died and was reborn into heaven. Sometimes it is the date the saint converted to Catholicism. Some times the date has no special significance for that specific saint.
All saints and blesseds are assigned a feast day by the Vatican's Sacred Congregation for the Causes of Saints.
The feast of Saints Peter and Paul - June 29.
The feast of All Saints is celebrated on November 1st. It is a day for Christians to honor and remember all the saints in heaven, both known and unknown.
Everyday there are dozens of saints that are memorialized. However, if that feast falls on a Sunday or another important feast day, or Good Friday, the saint's day is not observed.
No. There are thousands of saints, so it would be impossible for every single one of them to have their own feast day (unless we decided to devote each day of the calendar to several different saints). Instead, only those saints who had the greatest impact on the Church or around whom a fervent devotion has grown are celebrated with feast days in the liturgical calendar.
June 29 - the feast of Saints Peter and Paul
Nearly all the recognized saints have a designated feast day each year. However, there are thousands and thousands of saints in Heaven whose names are known only to God who do not have a feast day. All Saints Day recognizes all the unnamed saints.
November 1 is the feast of All Saints.
The feast day of St. Cyril, brother of St. Methodius, is February 14. He shares the date with St. Valentine and several other saints.
The feast day of the saint is the same as the saint's day. For example, the Feast of St. Patrick is also known as St. Patrick's Day - March 17.
There are more than a hundred saints named John and each one has a feast day.
No, it is not possible. You have at least 2 patron saints - the saint for whom you are named and the saint/saints who have their feast day on your date of birth. There are about 20 saints or more who have feast days every day of the year.
