I am building a transportation booking form, but I need to enter a pickup and drop-off date, but don't want to rely on the user to select the correct drop-off date. I want them to be able to select a pickup date and time, and then select a drop-off time. If that drop-off time is before midnight I want to populate the hidden drop-off date with the same pickup date, but if that drop-off time is on or after midnight populate the next day as the drop-off date. Is this a possibility?
