Calendars and Service Periods are required in order for your data to properly be displayed in online applications.
Create a New Calendar
New Calendars can be created by selecting Add Calendar. The only available field on a Calendar is Name. Name your Calendar something that clearly identifies what function it serves (such as School Year or Winter Shuttle,) and helps you organize your services.
Service Periods determine when a Calendar is in effect. A Calendar may have any number of Service Periods, provided they do not overlap.
On the desired Calendar, select Add a Service Period and select a start and end date. Depending on the type of Calendar used, multiple Service Periods may be required. For instance, a service that only operates when school is in session may have several Service Periods in a given year separated by breaks in service.
