使用Golang mgo查询日期范围之间的mongodb日期

I've tried following the solution mentioned here How can I query MongoDB with date range using mgo and Go? but I can't seem to get results for the dob range. "dob" in mongodb is stored as:

"dob": {
    "$date": "1967-06-28T00:00:00.000Z"
}

Without the dob query it works fine. I've tried switching $lt and $gt but still no luck. Does anyone know how to get this working? I've printed out dobLower and dobUpper and they both seem to be valid dates like 2000-06-28 21:57:06.666025643 +0000 UTC. The model for dob is Dob time.Time json:"dob" bson:"dob"

ageLower, err := strconv.Atoi(filters["ageLower"])
ageUpper, err := strconv.Atoi(filters["ageUpper"])
heightLower, err := strconv.Atoi(filters["heightLower"])
heightUpper, err := strconv.Atoi(filters["heightUpper"])
if err != nil {
    return nil, err
}

dobUpper := time.Now().AddDate(-ageLower, 0, 0)
dobLower := time.Now().AddDate(-ageUpper, 0, 0)

pColl := s.DB("mydb").C("profiles")

query := bson.M{
    "$and": []bson.M{
        bson.M{"active": bson.M{"$eq": true}},
        bson.M{"gender": bson.M{"$ne": u.Gender}},
        bson.M{"_id": bson.M{"$nin": u.HiddenProfiles}},
        bson.M{"_id": bson.M{"$ne": u.ProfileID}},
        bson.M{"dob": bson.M{"$gt": dobLower , "$lt": dobUpper}},
        bson.M{"height": bson.M{"$gt": heightLower, "$lt": heightUpper}},
    },
}

return pColl.Find(query).Select(bson.M{"first_name": 0}).All(&profiles)

Help will be much appreciated. Thanks.
