    The output should be a markdown code snippet formatted in the following schema, including the leading and trailing "\`\`\`json" and "\`\`\`":

    ```json
    {
            "type": string  // The type of leave requested by the user, including sick leave, personal leave, marriage leave, maternity leave, and compensatory leave. Personal leave is for personal reasons, excluding sick leave
            "start": string  // The start time of the user's leave request
            "end": string  // The end time of the user's leave request 
            "reason": string  // Why do users need to take leave.
    }
    ```
