Allerheiligen, or All Saints' Day, is a Christian holiday celebrated on November 1st. It honors all saints, known and unknown, who have attained heaven. The day is particularly significant in the Roman Catholic Church, where it is a time for reflection and remembrance of those who have passed away. In many countries, including Germany and Austria, people visit cemeteries to light candles and place flowers on the graves of loved ones. Traditional customs may include attending special church services and sharing meals with family. The holiday emphasizes the importance of community and the connection between the living and the deceased.
