const { from, to } = ranges[0];
    const selectedDays = day => DateUtils.isDayInRange(day, this.state) ||
    ranges.some(v => DateUtils.isDayInRange(day, v));

    return (
      <div>
        <h6>What dates might work for you?</h6>
        <div>
          {from &amp;&amp; to &amp;&amp;

        </div>
         550 ? 2 : 1}
          fromMonth={new Date()}
          disabledDays={DateUtils.isPastDay}
          onDayClick={this.handleDayClick}
          classNames={styles}
          selectedDays={selectedDays}
        /&gt;
