Based on the knowledge sources provided, I can explain the difference between Duration and Session Duration in Mixpanel:Session Duration is a specific property associated with Mixpanel's session tracking feature. It represents the time between the "Session Start" and "Session End" events for a given user session, measured in seconds. This property is automatically calculated by Mixpanel when sessions are enabled Docs Features > Sessions: Session Properties> .On the other hand, Duration (without the "Session" prefix) is not explicitly mentioned in the provided knowledge sources. In Mixpanel's context, duration typically refers to the time span between any two events or actions, not necessarily confined to a session.The key differences are:1. Scope: Session Duration is specifically tied to Mixpanel's session tracking feature, while Duration could refer to any time measurement between events.2. Calculation: Session Duration is automatically computed by Mixpanel when sessions are enabled, whereas a general Duration might need to be manually calculated or tracked.3. Usage: Session Duration is used to analyze user engagement within a defined session, while Duration could be used for various time-based analyses not limited to sessions.To use Session Duration in your analysis, you can leverage the "Session Duration (Seconds)" property that comes with Session Start and Session End events Docs Features > Sessions: Use Cases> .It's important to note that the exact definition of a session can vary based on your Mixpanel configuration (timeout-based, event-based, or property-based), which will affect how Session Duration is calculated Docs Features > Sessions: Session Computation Deep-Dive> .
