Calendar rarity, or internet hoax?

FROM TODAY'S PRINT EDITIONS:

July 2011A friend recently forwarded an email message alerting me to a calendar rarity: “This year, July has 5 Fridays, 5 Saturdays and 5 Sundays. This happens once every 823 years.” Pretty cool, except that it’s not true.

It’s yet another internet hoax, and it pops up every few months. Any month with 31 days that starts on Friday has five Fridays, Saturdays and Sundays. For any such month, the repeats come in interval cycles of six, five, six and then 11 years. The next July with five full weekends is in 2016.

I seen this and things like it several times before. With the Internet, it's so easy to verify or refute the claim. I've never understood why it gets traction.

FR: I agree. A very good place to check on these Internet myths is www.snopes.com

I wish your post about "more 90s due this week" was a hoax, but alas, it is not.

A neighbor shared an interesting metaphor for this weather: it's like living in a dog's mouth.

Blech!

FR: Eeww! But true.
