        const timeValue = new Date(value);

        const betweenTime = Math.floor((today.getTime() - timeValue.getTime()) / 1000 / 60);
        if (betweenTime < 1) return '방금전';
        if (betweenTime < 60) {
            return `${betweenTime}분전`;
        }

        const betweenTimeHour = Math.floor(betweenTime / 60);
        if (betweenTimeHour < 24) {
            return `${betweenTimeHour}시간전`;
        }

        const betweenTimeDay = Math.floor(betweenTime / 60 / 24);
        if (betweenTimeDay < 365) {
            return `${betweenTimeDay}일전`;
        }

        return `${Math.floor(betweenTimeDay / 365)}년전`;
 }
