title: How to check if the current date is the first of the month
body: <p>I'm trying to write a function which involves checking if the current date is the first of the month such as  01/03/2015 for example and then run something depending if it is. </p>
  
  <p>It doesn't matter whether it is a date or calendar object, I just want to check if the current date when the code is run is the first of the month</p>
