Claim: Facebook will be closed for maintenance at the end of February.
Example:[Collected on Facebook, February 2013]
WARNING!! Facebook will be closed for maintenance from February 29th to 31st!! Facebook wants YOU to Share this message with at least 15 of your friends for the best chance of alerting everyone. Many people will try to log in from February 29 to 31, just to find the site closed down for those days with no warning.
Origins: Much as we dislike having to spoil a joke by explaining its punchline (again!), we'll go on record as noting that this item about Facebook's closing for maintenance during the last three days of February is just a bit of silly humor. February only ever has 28 or 29 days, so the dates of February 30 and February 31 never occur. A leap year which adds an extra day to the usual number of 28 days in February (thus creating a February 29) occurs only once every four years, and 2013 is not one of those years. (The next leap year will be 2016.)
