      let day = new Date(
        Date.parse(date.toLocaleDateString().replace(/-/g, "/"))
      );
      let seperator1 = "/";
      let startDay = nowYear + seperator1 + "9" + seperator1 + "1";
      let endDay = nowYear + seperator1 + "11" + seperator1 + "15";
      let start = new Date(Date.parse(startDay.replace(/-/g, "/")));
      // console.log(startDay.replace(/-/g, "/"));
      // console.log('111')
      // console.log(Date.parse(startDay.replace(/-/g, "/")));
      // console.log(new Date(Date.parse(startDay.replace(/-/g, "/"))));
      let end = new Date(Date.parse(endDay.replace(/-/g, "/")));
      if (day < start || day > end) {
        return false;
