The "Service Type" in DocketCalendar refers to the method of service used in the filing of a case. This is significant because procedural rules in many courts require the addition of a certain period of time to the calculation of related deadlines, based on the method of service. For instance, this could include methods like personal service, electronic service, service by mail, etc.

DocketCalendar acknowledges this variation in deadline calculations by introducing what is known as a "service type offset." This offset is the additional time added to a deadline based on the service type. The service type matters because it affects how deadlines are calculated and ensures that all deadlines are accurate and in compliance with the specific procedural rules of the court handling the case​​.
