import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.opensymphony.workflow.InvalidInputException
import com.atlassian.jira.web.action.util.CalendarResourceIncluder

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
def startDateField = customFieldManager.getCustomFieldObjectByName("Impact Start")
def startDateValue = issue.getCustomFieldValue(startDateField)
def dueDateField = customFieldManager.getCustomFieldObjectByName("Impact End")
def dueDateValue = issue.getCustomFieldValue(dueDateField)
Calendar calendar = Calendar.getInstance(TimeZone.getDefault())
log.warn "starDateValue ${startDateValue}"

calendar.setTime(startDateValue)
int startDateDayOfWeek = calendar.get(Calendar.DAY_OF_WEEK)
log.warn "starDateValueweek ${startDateDayOfWeek}"
calendar.setTime(dueDateValue)
int dueDateDayOfWeek = calendar.get(Calendar.DAY_OF_WEEK)

// validation due date
if (dueDateValue != null ){
if(startDateValue > dueDateValue){
invalidInputException = new InvalidInputException("Due Date must be greater than Start Date")
}
}

// validation start date
if (startDateValue != null){
if(startDateValue > dueDateValue){
invalidInputException = new InvalidInputException("Due Date must be greater than Start Date")
}

if (issue.dueDate?.before(Calendar.getInstance().getTime())) {
invalidInputException = new InvalidInputException("Due date must be in the future.")

Hello @Alvin Parreno

Try to define startDateValue and dueDateValue  as a Date.

def startDateValue = issue.getCustomFieldValue(startDateField) as Date

Hi @Alvin

Already you have been fetched the values of StartDateFieldValue and EndDdateFieldValue now chk that both field value should not be empty.

if(EndDataFieldValue > StartDateFieldValue) 
{
 
flag = true;
 
}
if(flag)
{
return true;
}
else
{
throw new InvalidInputException("The " + ComponentAccessor.getCustomFieldManager().getCustomFieldObject(new Long(XXXX)) + " should be greater than " + ComponentAccessor.getCustomFieldManager().getCustomFieldObject(new Long(XXXX)));
}
