Students and parents follow our class schedules

Education and Sports

We're a private school in the Midwest. We initially started with publishing the class schedules for students and parents to follow. The number of subscribers isn't key to us, the service is. The feedback from students and parents is that they love it. It keeps them in the loop. We are automatically syncing the class schedule into CalendarX using our existing planning software. We have expanded our schedules to include all the sports we offer too.

Events and Meeting Planning


Our company employs close to 90,000 people across the world and produces more than 55,000 products. Being a big organization, we constantly need to train our employees to be up to date with safety and how-to procedures. Several times a week we offer our employees to participate in online training courses. Our employees can follow live seminars in their calendar. By centralizing our courses, we save money and make teaching more effective / specialized.
