NEBRASKA -- A holy day and a holiday are set to collide this Wednesday. Valentine’s Day and Ash Wednesday fall on the same day, which is a rare occurrence for the Christian holy day.

Ash Wednesday falling on the same day as Valentine’s Day, while rare, has happened this century.

The two days intertwined in 2018, 2024, and will again in 2029.

So how do the lovers' holiday and the religious holy day end up on the same day?

Ash Wednesday is not set for a specific date.

According to the United States Conference of Catholic Bishops, Easter is celebrated on the first Sunday after the full moon, which is the first full moon occurring on or after the spring equinox on Mar. 21.

Hence why Easter falls between Mar. 22 and Apr. 25.

To find the date for Ash Wednesday, they go back six weeks for the first Sunday of Lent and back an additional four days to find Ash Wednesday.

But what does this mean for Catholics and Christians wanting to celebrate both?

Not all Christians celebrate Ash Wednesday and those that do attend a church service where the priest or minister draws a cross of ashes on their forehead.

For Catholics, the day marks a day of fasting and abstaining from meat on Fridays.

As far as celebrating Valentine’s Day on Wednesday this year, Catholics may have to hold off on the chocolates and candies.

Back in 2018 when the same occurrence happened, the Roman Catholic bishop of Providence Bishop Thomas Tobin told AP Ash Wednesday has the priority and recommended to celebrate Valentine’s Day on Fat Tuesday.
