In ClassTag, you can create as many events you would like and add the dates for each. You would need to do it multiple times and specify the date of each event. For example, if you are planning to have four parent-teacher conferences for the entire school year, you need to create four parent-teacher conferences and configure each one with the date and time.
NOTE: When you create an event, parents will automatically see it on their “Activities” page but it won’t be added yet on the Weekly Summary they receive until the week when the event will happen.
