      Online Wheat Growing Degree Day Calculator    
                       
Calculate the Cumulative Growing Degree Days starting from your planting date to any ending date within the growing season    
Range starting from 10/1/2003 --------------> 7/04/2004          
Range starting from 10/1/2004 --------------> 7/04/2005          
Range starting from 10/1/2005 --------------> 7/04/2006     GDD = Ta - Tbase, if Ta is greater than Tbase    
  Planting Date     End Date       GDD = 0, if Ta is less than or equal to Tbase    
  Month Day Year   Month Day Year   Where: Tbase = temperature base, usually 40F    
      Ta = average temperature    
                  Ta = (Tmax + Tmin) / 2
