March 13 is Coming: Open an Umbrella Indoors Day

Well, this is the year to ward off bad luck. Not only can we celebrate Friday the 13th by opening up black umbrellas indoors, but I now find that--UNRELATED to it being Friday--March 13 has been celebrated at National Open an Umbrella Indoors Day, with much of the same concern for all the care one must take with umbrellas:

According to some, it's only considered bad if any of the following apply:

• The umbrella was a gift.
  
• The umbrella is black.
  
• The umbrella has never been used outdoors.
  
• There is a sick person in the house.

Other bad luck umbrella superstitions:

• Never give an umbrella as a gift.
  
• Never pick up an umbrella you dropped (ask someone to do it for you).
  
• Never place your umbrella on a table or a bed.
  
• If a single woman drops her umbrella, she'll never marry.

Trying to run down the origin of this and am now finding that the Dull Men's Club thinks all of March is Umbrella Month:

March is the month to honor one of the most versatile and underrated inventions of the human race. The month is dedicated to the use of and conversations about umbrellas. If you belong to a Dull Men’s Club in your community, have umbrellas as a discussion topic for one of your meetings this month.

But, cannot find out anything more! Let us get to the root of this one.
