Holy Day on 4th November - if it exists, what religion is it for?

Question

A friend of mine was asking another friend about it and I know nothing of a holy day, I must admit. So I'm posting it here.

Answer 1

November 4th is the feastday of St. Charles Borromeo: http://www.catholic.org/saints/saint.php?saint_id=212

Answer 2

I suspect your friend is mistaken.

1. Wikipedia does not show it as a date of major significance for any predominant religion.

2. I wonder whether your friend was getting confused about Diwali, which has a shifting date - in 2007 it is on Friday 9 November, and last year it was on Sunday 22 October.

3. There is also an outside chance that your friend means 5 November. That is Guy Fawkes Night in the UK (and some former colonies) - although it is largely secular in its celebration, it does commemorate the defeat of a Catholic conspiracy to assassinate the English Protestant King in 1605. However I doubt that your friend means that.

Answer 3

The Catholic Church celebrates All Saints day on November 1st. National Unity Day is celebrated on Nov. 4th this year. That is not a religious holiday
