title: How to use dates and logical operators in Spotfire Custom Expressions
body: <p>I'm trying to add a new calculated column in Spotfire using an expression, where if a date is greater than a specified date, then the expression should return true. However, how do you tell the Custom Expression builder that you want to do this?</p>
  
  <p>The syntax should be something like if <code>([datea] &gt; 1-1-2014, 1, 0)</code>, but I am struggling what to delimit the date in the expression: I've tried double quotes, single squares, hashes (#) but with no luck. </p>
  
  <p>Any thoughts? </p>
