Reformation Day commemorates the beginning of the Protestant Reformation. It marks the day in 1517 when Martin Luther, a German monk and theologian, is traditionally believed to have nailed his 95 Theses to the door of the Wittenberg Castle Church.

All Saints' Day is a Christian holy day dedicated to honoring all saints, both known and unknown, who have attained Heaven. It is observed by the Roman Catholic Church, Eastern Orthodox Church, Anglican Communion, and many other Protestant denominations.
