Why doesn't visual studio see one of my classes C++?

Question

I have two classes Task and TaskDate. It seems like visual studio doesn't see TaskDate. Did I do something wrong or why doesn't it seem to find it? I get the error at line 11: 'date':unknown override specifier, like date wouldn't have a type

This is Task.h

#ifndef TASK_H
#define TASK_H
#define _CRT_SECURE_NO_WARNINGS
#include <string>
#include "TaskDate.h"

class Task
{
private:
    std::string id, title, type, status;
    TaskDate date;

public:
    Task();
    virtual ~Task();
    Task(std::string id, std::string title, std::string type, std::string status, TaskDate date);

    std::string getTaskID() { return id; }

    std::string getTitle() { return title; }

    std::string getType() { return type; }

    std::string getStatus() { return status; }
    
    TaskDate getDate() { return date; }

    std::string toString();
};

#endif

This is TaskDate.h

#ifndef TASKDATE_H
#define TASKDATE_H

#include "Task.h"


class TaskDate
{
public:
    int day;
    int month;
    int year;
    TaskDate();
    TaskDate(int nday, int  nmonth, int  nyear);
};
#endif
