This week, Protestants observe Reformation Sunday (October 27), which recalls the day in 1517 when Martin Luther nailed his 95 theses to a church door in Wittenberg. November 1 is All Saints Day, when Christians honor martyrs and saints, followed by All Soul’s Day on November 2.

On November 3, Hindus around the world begin the five-day celebration of Diwali, the festival of lights. Diwali  is one of the most well-loved of all Hindu festivals and is held in honor of Lakshmi, the goddess of wealth.

Also this week, depending on the sighting of the new moon, Muslims mark the Islamic New Year.
