The Day of Saint Peter and Saint Fevronia (Russian: День Святых Петра и Февроньи / Den' Svyatyh Petra i Phevronii) also known as the Day of Family, Love and Faithfulness (Russian: Де́нь семьи́, любви́ и ве́рности / Den' sem'i lyubvi i vernosti), the Orthodox patrons of marriage, was officially introduced in Russia in 2008.

Fevronia (Greek Φεβρωνία) was beautiful, pious and good, plus she was a wise woman, she knew the properties of herbs and could cure ailments.

Since she was a commoner, the prince believed that he could not do such a thing because of his noble status, but he desperately wanted to be cured, so he vowed to marry her after the healing.

This marriage was marked by Peter and Fevronia's profoundly deep love for one another, which they nourished by God's grace for their whole lives.

Peter, after he heard of the intentions of separating him from the beloved wife, chose to voluntarily relinquish the power and wealth and go with her in exile.

Part of Saint Valentine’s relics was deposited in the Cathedral of Christ the Saviour in Moscow several years ago, during the life of late Patriarch Alexiy II.

According to a recent opinion poll, Saint Valentine's Day has become popular among Russians, yet this holiday has more opponents than supporters.

According to sociological data, the demand for flowers, souvenirs and perfume in Russia grows by almost 15% ahead of All Lovers’ Day.
