"pocket full of money"

This dumb "pocket full of money" thing came up in my tumblr feed.

The only time you will witness this phenomenon in your life.

This year, the month of August will count 5 Fridays, 5 Saturdays, and 5 Sundays. This phenomenon occurs only once every 823 years. Chinese people call it: 'Pocketful of money!'

blah blah reblog blah send this to all your friends blah

This happens way, WAY more often than every 823 years. Here is the list of Friday, August 1sts from 1900 to 2100. The last time was in 2008 and the next time (after this year) will be 2025.

irb(main):007:0> (1900..2100).collect { |y| Date.new(y,8,1) }.reject {|d| not d.friday?}
