        // calculate days
        days = Math.floor(diffInMilliSeconds / 86400);
        diffInMilliSeconds -= days * 86400;

        difference = '';

        if (days > 0) {
            difference += (days === 1) ? `${days} Day ` : `${days} Days `;
        }

        return 'Calculate = ' + difference;
    }
