Usage

What is Hallowmas? Hallowmas is an older name for All Saints’ Day, a Christian holiday in honor of all the Christian saints. It originated as a holiday of the Catholic Church, but it is also observed by some other Christians. The day after All Saints’ Day is All Souls’ Day, a Christian holiday of solemn prayer for all dead persons. Other names for the day include Allhallows and Allhallowmas. The night before was known as Allhallows Eve, which is where the word Halloween comes from.
