title: Change DataFrame Dates From UK to US in Python
body: <p>I have a set of dates that I would like to change in a dataframe. I think some are incorrectly being read as British dates and I don't know how to change them over. </p>
  
  <p>For instance, 01/04/2018 (April 1st) is being read as a the fourth of January. I've tried to even hackjob this in Excel by using TextToConvert, but it still reads the date as the 4th of January when I mean the 1st of April. Other dates such as the 22/04/18 are read just fine as the 22nd of April. Everything with a day value under 12 though is sadly flipped. </p>
  
  <p>Please advise on a clean way to change this in Python. None of the parseDT methods I've tried have worked. The data is currently a datetime type. </p>
  
  <p>Thank you!</p>
