Ash Wednesday, Valentine's Day fall on same day: What does it mean for fasting?

PHILADELPHIA (WPVI) -- Valentine's Day and Ash Wednesday fall on the same day this year.

Yes, it's Valentine's Day, the fixed annual celebration of love and friendship, marked by cute couples, eager elementary school students - and critics who deride its commercialization. But it also happens to be Ash Wednesday, a holy day of prayer and fasting observed by Catholics that signals the start of Christianity's most penitent season.

Many Catholics are now wondering, however, if the church will make an exception to the fasting obligation for the holy day.

WHY IS ASH WEDNESDAY ON VALENTINE'S DAY THIS YEAR?

Ash Wednesday is not a fixed date. Its timing is tied to Easter Sunday, and for most Christians, Easter will fall on March 31 this year.

Easter also moves annually, swinging between March 22 and April 25 based on a calendar calculation involving the moon.

The U.S. Conference of Catholic Bishops lays it out: "Easter is celebrated on the first Sunday after the Paschal full moon, which is the first full moon occurring either on or after the spring equinox (March 21). ... To find the date for Ash Wednesday, we go back six weeks which leads to the First Sunday of Lent and four days before that is Ash Wednesday."

This year, that happens to be Feb. 14.

WHAT HAPPENS ON ASH WEDNESDAY?

Not all Christians observe Ash Wednesday. For those who do, they typically attend an Ash Wednesday church service, where a priest or other minister draws a cross - or at least what is intended to look like one - of ashes on their forehead. The distribution of ashes underscores human mortality, among other themes.

It's an obligatory day of fasting and abstinence for Catholics. The abstinence restrictions are continued on Fridays during Lent, which is the period of repentance and penance leading up to Holy Week observances - most significantly their belief in the crucifixion of Jesus and his resurrection from the dead.

WHERE DO THE ASHES COME FROM?

Typically, the ashes are from the palms used on Palm Sunday, which falls a week before Easter, according to the Evangelical Lutheran Church in America.

Ashes can be purchased, but some churches make their own by burning the palms from prior years. For example, several parishes and schools in the Chicago Catholic Archdiocese plan to hold palm burning ceremonies this year.

CAN CATHOLICS CELEBRATE VALENTINE'S DAY ON ASH WEDNESDAY?

The Archdiocese of Philadelphia told Action News that Ash Wednesday is one of the most solemn days on the Christian calendar, and no exemptions are being granted.

So for anyone celebrating the holy day, be sure to treat yourself to a date night or box of chocolates on another day.

WHO WAS ST. VALENTINE?

The history of Valentine's Day and St. Valentine is a bit murky, but the holiday began as a liturgical feast day for a third-century Christian martyr, according to Lisa Bitel, a history and religion professor at the University of Southern California.

In the Conversation, her article titled, " The 'real' St. Valentine was no patron of love," explains there may have been more than one St. Valentine executed for their faith in the same time period, but none of them appear to have been romantics. The emphasis on love appears to have come later.
