Not all saints have a designated feast day. In the Catholic Church, recognized saints typically have a feast day to commemorate their lives and contributions, but some lesser-known saints may not have one. Additionally, certain local or regional saints may have feast days that are not universally observed. Overall, while many saints are celebrated with feast days, it varies depending on recognition and tradition.
With the vast majority of early saints, the date of death is unknown. The feast day MAY be the day the saint was reborn into Heaven (when they died) but this is not the rule. It may be the anniversary day of some other event in their life or it may have no significance at all. It would be impossible to give the number of saints who died on their feast day as it is really unknown.
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.
All saints and blesseds are assigned a feast day by the Vatican's Sacred Congregation for the Causes of Saints.
The day of a saint's feast is sometimes the commemoration of the day they died or some other important event in their lives. Other days are picked somewhat randomly, as in the case of John the Apostle as we know neither the date of his birth or of his death. On any day of the year there may be 20 or more saints memorialized.
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.
Joseph as two feast days - March 19 and May 1 which is the feast day of Saint Joseph the worker.
June 29 - the feast of Saints Peter and Paul
Originally, the feast date of Thomas Aquinas was on March 7, the day he entered heaven. It is unknown to me the reason for the change. You need to know that there are thousands and thousands of saints and each one has a specific feast day. That means that, on any given day, there may be dozens of saints who are celebrated that same day.
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.
