Outline
Message claims that July 2011 has 5 Fridays, 5 Saturdays and 5 Sundays and that this combination of days only occurs once in 823 years.
Brief Analysis
It is perfectly true that July 2011 has 5 Fridays, 5 Saturdays and 5 Sundays. However, such a combination occurs far more often than every 823 years. The last occurrence was in July 2005 while the next occurrence will take place in July 2016. The message is just a revamped version of very similar- and equally erroneous – messages about August and October 2010.
Example
Subject: July 2011: INTERESTING!
This year, July has 5 Fridays, 5 Saturdays and 5 Sundays. This happens once every 823 years. This is called money bags. So, forward this to your friends and money will arrive within 4 days. Based on Chinese Feng Shui the one who does not forward ….. will be without money. I’m not taking any chances!
