👺请假天数计算

计算请假天数，去除周六天、节假日，计算调休时间。

上午固定时间08：30 下午固定时间14：00

🙈直接上代码

<template>
  <div>
    <span>{{ days }}</span>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      // 节假日
      festival: ['2022-01-03', '2022-01-31', '2022-02-01', '2022-02-02', '2022-02-03', '2022-02-04', '2022-04-10', '2022-04-05', '2022-06-03', '2022-09-12', '2022-10-03', '2022-10-04', '2022-10-05', '2022-10-06', '2022-10-07'],
      // 调休日期
      weekendWorkDay: ['2022-01-29', '2022-01-30', '2022-04-02', '2022-04-24', '2022-05-07', '2022-10-08', '2022-10-09'],
      // 节假日转时间戳
      festival_list: [],

      weekendWorkDay_list: [],
      days: ''
    }
  },

      var diffDay = (endday - startday) / (1000 * 60 * 60 * 24) + 1
      // 周末周六天数+节假日
      var weekEnds = 0
      if (start > end) return 0

      // 循环相差天数
      for (var i = 0; i < diffDay; i++) {
        if ((startday.getDay() === 0 || startday.getDay() === 6 || this.festival_list.includes(startday.valueOf())) && !this.weekendWorkDay_list.includes(startday.valueOf())) {
          weekEnds += 1
        } else {
