A degree day (also called heat unit or thermal unit) is a measure of the amount of heat that accumulates above a specified base temperature during a 24-hour period, and cumulative degree days (DD) are the total number of DD that have accumulated since a designated starting date, and they are calculated simply by adding the number of DD that accumulate each day: and if maximum temperature for the day never rises above the base temperature then no development occurs, and zero DD accumulate (Herms, 2004).
Daily maximum temperature is less then lower threshold no degree day accumulations.
