This is the String#[] method http://www.ruby-doc.org/core-2.2.0/String.html#method-i-5B-5D monthname[0..-6] returns the string from the first character until the one 6 from the end (negative indexes count from the end of strings) monthname[3..8] returns from index 3 (i.e. the 4th character) until the one at index 8 So if your string is "06 2015" then monthname[0..-6] is "06" and monthname[3..8] returns "2015" (given the length of the string monthname[3..6] would return the same string) Using strings that have to be torn apart like this does seem a little bit obtuse though.
