db.collection.aggregate([
  {
    $match: {
      "Att Date": {
        $gte: "2019-09-01",
        $lte: "2019-09-30"
      }
    }
  }

Answer 1

您正在比较 "2019-09-01", 一个字符串与 ISODate("2019-09-11T18:30:00Z") 一个日期

尝试比较日期和日期

db.collection.aggregate([
  {
    $match: {
      "Att Date": {
        $gte: ISODate("2019-09-01"),
        $lte: ISODate("2019-09-30")
      }
    }
  }
])
