Skuid Community,

In case anyone arrives here.  Another option is a custom formula function.  Here is the code for a Custom Formula Field function to add days to a date field:

skuid.formula.Formula (
  ‘ADD_DAYS’,
  function (fieldName, daysToAdd) {
      if(fieldName !== null && fieldName !== undefined ) {
      if(daysToAdd===null || daysToAdd===undefined || daysToAdd===‘’) {
      daysToAdd = 0;
      }
    var jsDate = skuid.time.parseSFDate(fieldName);
    //add days
    jsDate.setDate(jsDate.getDate() + daysToAdd);
    //convert from Javascript date back to Salesforce date
        return skuid.time.getSFDate(jsDate);
    } else {
        return null;
    }
  },{
    namespace: ‘dateFunctions’,
    numArgs : 2,
    returnType : ‘date’
  }
);
//
// Usage
// dateFunctions__ADD_DAYS({{Date_Field__c}}, 30)
// dateFunctions__ADD_DAYS({{Date_Field__c}}, {{daysToAdd}})
//
// Where’
// {{Date_Field__c}} is a field of type = DATE
// {{daysToAdd}} is a NUMBER or TEXT field represting the number of days to add

Thanks,

Bill
