All Hallows’ Eve is being observed on October 31 as people around the world celebrate Halloween with costumes, pumpkin decorations and traditional activities. The occasion falls one day before All Saints’ Day, a Christian observance dedicated to honouring saints. Although Halloween is now widely associated with parties and trick-or-treating, its original name reflects a religious tradition that developed centuries ago.
All Hallows’ Eve and Halloween refer to the same occasion. The name comes from older English words connected with saints and the evening before a religious festival. Over time, the observance developed into a celebration influenced by Christian customs, European folklore and modern popular culture.
What Does All Hallows’ Eve Mean?
The term All Hallows’ Eve means the evening before All Saints’ Day, which is celebrated on November 1 in many Western Christian churches.
The word “hallow” is an old English term referring to a saint or holy person. “Eve” means the evening before a significant event or religious observance.
The original expression, All Hallows’ Even, was gradually shortened to Hallowe’en. The modern spelling, Halloween, developed from this shortened form.
The name therefore has a direct connection to Christianity, even though many present-day Halloween activities are secular.
Why Is All Hallows’ Eve Celebrated on October 31?
All Hallows’ Eve takes place on October 31 because it precedes All Saints’ Day on November 1.
In Western Christianity, the period is part of Allhallowtide, which includes All Hallows’ Eve, All Saints’ Day and All Souls’ Day.
All Souls’ Day is observed on November 2 and is traditionally associated with prayers for the faithful departed.
These three observances developed within Christian religious practice and remain important in several denominations.
However, Halloween celebrations have expanded beyond their religious origins, particularly in countries such as the United States, Canada, Ireland and the United Kingdom.
How Did All Hallows’ Eve Become Halloween?
The transformation of All Hallows’ Eve into Halloween took place gradually through changes in language and cultural traditions.
The name Hallowe’en became common in Scotland and other English-speaking regions before the simplified spelling Halloween gained widespread use.
The celebration also became associated with customs connected to the ancient Celtic festival of Samhain.
Samhain marked the transition from the harvest season into winter and was traditionally observed around the beginning of November.
Historical accounts describe seasonal gatherings, bonfires and beliefs involving supernatural activity.
Although Halloween is frequently linked to Samhain, historians note that the relationship between ancient Celtic customs and modern Halloween traditions is complex.
Why Are Costumes and Pumpkins Associated With Halloween?
Halloween costumes developed through several European traditions, including disguises, seasonal performances and customs involving supernatural figures.
In parts of Ireland and Scotland, people participated in guising, a practice involving costumes and visits to neighbouring homes.
These customs later influenced modern trick-or-treating, particularly after Halloween became popular in North America.
Pumpkin carving also developed from older traditions involving carved turnips and other vegetables.
Irish immigrants helped introduce these customs to the United States, where pumpkins became a more common choice because they were widely available.
Today, carved pumpkins, known as jack-o’-lanterns, are among the most recognisable Halloween decorations.
Is All Hallows’ Eve a Religious Holiday?
All Hallows’ Eve has Christian religious origins, but its modern observance varies considerably.
Some Christians attend church services, hold prayer gatherings or prepare for All Saints’ Day.
Others participate in community events, costume parties and family celebrations without any religious connection.
Halloween has also become an important commercial and cultural occasion, particularly in the United States.
Retailers, entertainment companies and local communities organise seasonal activities involving decorations, costumes and themed events.

All Hallows’ Eve falls on Saturday, October 31, 2026.
All Saints’ Day follows on Sunday, November 1, while All Souls’ Day is observed on Monday, November 2.
Halloween celebrations are taking place across numerous countries, with activities ranging from traditional religious observances to public festivals and neighbourhood trick-or-treating.
