What are the 3 Days of Darkness?

And they say to the mountains and the rocks: Fall upon us, and hide us from the face of him that sitteth upon the throne and from the wrath of the Lamb: For the great day of their wrath is come, and who shall be able to stand? (Revelations 6:16-17)

Blessed Anna Maria Taigi (1769–1837) is the most known mystic who described the Three Days of Darkness and describes the event in this way:

There shall come over the whole earth an intense darkness lasting three days and three nights. Nothing can be seen, and the air will be laden with pestilence which will claim mainly, but not only, the enemies of religion. It will be impossible to use any man-made lighting during this darkness, except blessed candles. He, who out of curiosity, opens his window to look out, or leaves his home, will fall dead on the spot. During these three days, people should remain in their homes, pray the Rosary and beg God for mercy. All the enemies of the Church, whether known or unknown, will perish over the whole earth during that universal darkness, with the exception of a few whom God will soon convert. The air shall be infected by demons who will appear under all sorts of hideous forms.

Marie-Julie Jahenny (1850-1941), known as the “Breton Stigmatist”, expanded upon the story of the Three Days of Darkness, saying that it will occur on a Thursday, Friday, and Saturday to strike at those outside their homes and those without a lit blessed candle of 100% pure wax. A Catholic home should keep such candles in stock for sick calls as well, should a priest need to visit a sick family member. These candles should be bought long in advance and blessed long in advance as well by a priest using the traditional blessing of candles. The English translation is as follows:

Our help is in the name of the Lord.

All: Who made heaven and earth.

P: The Lord be with you.

All: May He also be with you.

Let us pray.

Lord Jesus Christ, Son of the living God, bless + these candles at our lowly request. Endow them, Lord, by the power of the holy + cross, with a blessing from on high, you who gave them to mankind in order to dispel darkness. Let the blessing that they receive from the sign of the holy + cross be so effectual that, wherever they are lighted or placed, the princes of darkness may depart in trembling from all these places, and flee in fear, along with all their legions, and never more dare to disturb or molest those who serve you, the almighty God, who live and reign forever and ever.

All: Amen.

They are sprinkled with holy water.

While we certainly do not know the day when the end will come, we nevertheless must always be prepared by living and remaining in the state of sanctifying grace. Each of us will die one day - at any moment - and the state of our souls at that moment will determine an eventual eternity in Heaven or in Hell.
