The "Three Days of Darkness" is a prophecy in some Catholic mystical traditions predicting a future event when the earth will be covered by an intense darkness for three days and three nights. During this time, no natural or artificial light except specially blessed beeswax candles will work. It is said that those who leave their homes or look outside will die, and the air will be filled with pestilence and demonic activity. This prophecy is often linked to the period before the final judgment. Regarding when it will happen, there is no specific, universally accepted date for the event. Some modern claims and predictions have suggested dates around 2024 or 2025, but these are not supported by official Church doctrine and have been considered speculative or misleading. The prophecy is rooted in private revelations and mysticism, and the Catholic Church has not officially confirmed its authenticity or timing. In summary, the "Three Days of Darkness" is a mystical prophecy with no confirmed date for when it will occur, and claims about it happening in 2025 or any specific year are not officially recognized or scientifically substantiated.
