  "account": "Domain events are the result of listening to domain experts, representing something that has happened and that domain experts want to know about. When determining whether a domain event is important, listen for phrases like \"when...\", \"if that happens...\", \"inform me if...\", and \"notify me if...\". Domain events serve as a bridge to communicate domain occurrences to external systems, particularly when events need to be broadcast to other services and Bounded Contexts within an enterprise.\n\nWhen modeling domain events, the name should be derived from the ubiquitous language of the domain. If the event is the result of executing a command operation on an Aggregate, the event name should reflect the past occurrence of the command. The event should include a timestamp, and additional properties are determined by the team based on what is necessary to represent the event meaningfully.\n\nEvents are created by clients and represent past occurrences that are not the direct result of executing behavior on an Aggregate instance. These events can be modeled as part of an Aggregate's structure, making them immutable but allowing for the assignment of a unique generated identity.",

There is no direct definition, we can say that they are the result of listening to domain experts. And the final point is something happened and the domain experts want to know it.
