Hi there,
I have a problem, i have a dataset, in which there are time series from 2010- 
to 2014, like this:
-2014-01-30 15:39:46
-2012-04-20 14:49:02
  And so on .
I want to have a situation in which there are days of week expressed in word, 
because I have to calculate days of week and on the other hand week end. For 
example, i want :
-2014- 01 monday 15:39:46
-2012-04 saturday 14:49:02
Thanks guys
