Date strptime returns invalid date

irb, ruby

Solution

Yes, you are missing something: There are never 31 days in February, regardless of the year.

You have given it an invalid date.

Problem

Here is my IRB session ``` 1.9.2p290 :020 > Date.strptime("31-2-2010", "%d-%m-%Y") ArgumentError: invalid date ``` I have given the proper values, yet it is returning `ArgumentError`. Am I missing something here?
