title: Change Quarters as obtained in time series to financial quarters
body: <p>So I have a table as shown. It has a date quarter of the year and a SoldItems column. I would like to change it to words and also have it in Fiscal year quarters where Jan-Mar =Qtr4, Apr-Jun = Qtr1, Jul-Sep =Qtr2, Oct-Dec =Qtr3.</p>
  <pre><code>0   2019-01-01   1  23
  1   2019-01-02   1  87
  2   2019-01-03   1  54
  3   2019-01-04   1  63
  4   2019-01-05   1  14
  
  </code></pre>
  <p>How do I do that?</p>
