Gravity Forms Date Time Calculator —

This plugin adds the ability to use Date and Time fields in Gravity Forms calculations. Create complex and precise calculations based on any combination of Date, Time, and Number fields. Calculations can be used in any field that normally supports calculations, allowing you to build forms with flexible time-based pricing, track days and hours, determine the age of a customer based on their birth date, and any other calculation related to date and time.
