Holdover Calculator is a quick and accurate way to verify a holdover time. Manual holdover time calculations that were tedious, time consuming and often error prone, can now be completed with confidence in just a matter of seconds.
The input fields required for computations are presented in a user friendly and logical display. After completing the associated conditions, select “Calculate” to see your holdover time. All associated holdover chart notes are incorporated and prompts for additional required input are presented to the user when necessary.
