None of the previous answers  to this date  gives the correct difference in days between two dates   The one that comes closest is by thatdankent  A full answer would convert to i and then divide    Time now to i - 23 hours ago to i    86400  gt  gt  0   Time now to i - 25 hours ago to i    86400  gt  gt  1   Time now to i - 1 day ago to i    86400  gt  gt  1   In the question s specific example  one should not parse to Date if the time passed is relevant  Use Time parse instead

Rails has some built in helpers that might solve this for you  One thing to keep in mind is that this is part of the Actionview Helpers  so they wont be available directly from the console   Try this   lt   start time     2012-03-02 14 46 21  0100    gt   lt   end time       2012-04-02 14 46 21  0200    gt   lt    distance of time in words start time  end time     gt     about 1 month
