Populating data automatically into a calendar

I downloaded the “full calendar” plug-in. I am building a program to show “route” information. I want my users to be able to add clients/stops to the master list, that I have already created. I am now adding a feature to be able to see your clients on a calendar page. I want the calendar to auto-display the clients on a calendar according to the “day” information the user input.

master list page is “logged_in_route”
Desired calendar page to transmit data to is “logged_in_calendar”
Thanks!
