I have date something like this
"createdAt": "ISODate('2021-07-07T06:41:46.000Z')"
I have written below mongoose query to fetch records for today. But below query fetched empty.
let meeting = await Meeting.find({
createdAt : {$lt: new Date().toISOString(),$gte: new Date().toISOString()}
});
I have tried below one more way with static date, it worked. I want to fetch data on dynamic todays date.
let meeting = await Meeting.find({
createdAt : {
'$eq': new Date('2021-07-07T06:41:46.000Z')
}
});
Can someone help me on this
I'm assuming the type of "createdAt" field is Date in Mongoose schema (you should convert to Date if it wasn't the case).
Logic
When you want to filter documents on a specific day, you can use the condition:
0:00 the day <= createdAt < 0:00 the following day
For example, to filter meetings on 07/07/2021, the condition will be:
0:00 07/07/2021 <= createdAt < 0:00 08/07/2021
Coding
With that logic in mind, the code is pretty straightforward:
let today = new Date();
today.setHours(0,0,0,0); // set to 0:00
let tomorrow = new Date(today)
tomorrow.setDate(tomorrow.getDate() + 1)
let meeting = await Meeting.find({
createdAt : {$gte: today, $lt: tomorrow}
});
When working with date/time values then I recommend the moment.js library. Could be this one:
let meeting = await Meeting.find({
createdAt : {
$gte: moment().startOf('day').toDate(),
$lte: moment().endOf('day').toDate()
}
});
I have a Product collection stored in MongoDB. It has a attribute date :
const productSchema = new mongoose.Schema<ProductAttrs>({
date: {
type: Date,
required: true,
}
...
})
I would like to retrieve all products whose date is within last 6 minutes comparing with current time. What is the efficient way to retrieve that in mongoose ?
I am using express.js + typescript + mongoose v5.11 in my project.
You must use Mongoose to search every record where the time is greater than now - 6 minutes.
I have no way to test it, but the query should look something like this:
const sixMinutes = (6*60*1000); // 6 minutes
let sixMinutesAgo = new Date();
sixMinutesAgo.setTime(sixMinutesAgo.getTime() - sixMinutes);
const products = Product.find({
date: {
$gte: sixMinutesAgo
}
})
If your MongoDB server version is 5.0 you could use the new operator $dateDiff. In this case it is very handy and you do not even need an aggregate:
db.collection.find({
"$expr": {
"$lte": [
{
"$dateDiff": {
startDate: "$date",
endDate: new Date(),
unit: "minute"
}
},
6
]
}
})
It allows you to specify the unit field, which makes the query very straightforward in my opinion.
$expr evaluates an expression and returns true or false, just that. If the expression result is true then the row is returned, otherwise it is not.
$lte means less than or equal (the <= operator) and it returns true only when the first argument is less than or equal the second operator. Basically, this is what it does in pseudocode:
foreach doc in collection
if (minute)(currentDate - document.date) <= 6 then
return document
My application will allow user to create coupons.
Coupon will be valid in datefrom and dateto period.
The thing is that every coupon should be valid for selected days, not hours.
For example since Monday(2016-06-12) to Tuesday(2016-06-13), so two days.
How should I store dates on server side and then compare it using $gte clause in Mongoose?
Thank you :-)
{ "_id" : 1, "couponStartDate" : ISODate("2016-06-26T18:57:30.012Z") }
{ "_id" : 2, "couponStartDate" : ISODate("2016-06-26T18:57:35.012Z") }
var startDate = new Date(); // I am assuming this is gonna be provided
var validDate = startDate;
var parametricDayCount = 2;
validDate.setDate(validDate.getDate()+parametricDayCount);
CouponModel.find({couponStartDate: {$gte: startDate, $lte: validDate}}, function (err, docs) { ... });
You can store expiration time as UNIX timestamp. In your Mongoose model you can use expiration : { type: Number, required: true}
If you have user interface for creating coupons then you can configure your date picker to send time in UNIX timestamp.
Or If you are getting Date string then you can use var timestamp = new Date('Your_Date_String');
And for calculation of Days you can use Moment JS. Using this you can calculate start of the date using .startOf(); and end of date using .endOf();
Timestamp return from Moment JS can be used for Mongoose query like $gte : some_timestamp and $lte : some_timestamp
If you want to validate the coupon before it is persisted, you can create a max / min value for the date field:
See this sample from official mongoose documentation on DATE validation:
var s = new Schema({ dateto: { type: Date, max: Date('2014-01-01') })
var M = db.model('M', s)
var m = new M({ dateto: Date('2014-12-08') })
m.save(function (err) {
console.error(err) // validator error
m.dateto = Date('2013-12-31');
m.save() // success
})
Hint: use snake_case or camelCase for field names
I have saved my date as timestamp, using the below logic:
var timestamp = Math.floor(new Date().getTime()/1000);
timestamp =145161061
Can any one help me out with the query?
I need to find records between dates and my date is stored in timestamp format as shown above.
If you have specified the type of the field to be date, then even if you store the date by giving the time stamp, it will get stored as Date.
To do a range query on date you can simply do something like this:
db.events.find({"event_date": {
$gte: ISODate("2010-01-01T00:00:00Z"),
$lt: ISODate("2014-01-01T00:00:00Z"),}})
But then if you have specified it as Number, then you can simply do a range query on the number like this :
db.events.find({"event_date": {
$gte: 145161061,
$lt: 145178095,}})
You can try kind of this query:
var startTime = 145161061;
var endTime = 149161061;
Books.find({
created_at: {
$gt: startTime,
$lt: endTime
}
});
Is it possible to query for a specific date ?
I found in the mongo Cookbook that we can do it for a range Querying for a Date Range
Like that :
db.posts.find({"created_on": {"$gte": start, "$lt": end}})
But is it possible for a specific date ?
This doesn't work :
db.posts.find({"created_on": new Date(2012, 7, 14) })
That should work if the dates you saved in the DB are without time (just year, month, day).
Chances are that the dates you saved were new Date(), which includes the time components. To query those times you need to create a date range that includes all moments in a day.
db.posts.find({ //query today up to tonight
created_on: {
$gte: new Date(2012, 7, 14),
$lt: new Date(2012, 7, 15)
}
})
...5+ years later, I strongly suggest using date-fns instead
import endOfDayfrom 'date-fns/endOfDay'
import startOfDay from 'date-fns/startOfDay'
MyModel.find({
createdAt: {
$gte: startOfDay(new Date()),
$lte: endOfDay(new Date())
}
})
For those of us using Moment.js
const moment = require('moment')
const today = moment().startOf('day')
MyModel.find({
createdAt: {
$gte: today.toDate(),
$lte: moment(today).endOf('day').toDate()
}
})
Important: all moments are mutable!
tomorrow = today.add(1, 'days') does not work since it also mutates today. Calling moment(today) solves that problem by implicitly cloning today.
Yeah, Date object complects date and time, so comparing it with just date value does not work.
You can simply use the $where operator to express more complex condition with Javascript boolean expression :)
db.posts.find({ '$where': 'this.created_on.toJSON().slice(0, 10) == "2012-07-14"' })
created_on is the datetime field and 2012-07-14 is the specified date.
Date should be exactly in YYYY-MM-DD format.
Note: Use $where sparingly, it has performance implications.
Have you tried:
db.posts.find({"created_on": {"$gte": new Date(2012, 7, 14), "$lt": new Date(2012, 7, 15)}})
The problem you're going to run into is that dates are stored as timestamps in Mongo. So, to match a date you're asking it to match a timestamp. In your case I think you're trying to match a day (ie. from 00:00 to 23:59 on a specific date). If your dates are stored without times then you should be okay. Otherwise, try specifying your date as a range of time on the same day (ie. start=00:00, end=23:59) if gte doesn't work.

You can use following approach for API method to get results from specific day:
# [HTTP GET]
getMeals: (req, res) ->
options = {}
# eg. api/v1/meals?date=Tue+Jan+13+2015+00%3A00%3A00+GMT%2B0100+(CET)
if req.query.date?
date = new Date req.query.date
date.setHours 0, 0, 0, 0
endDate = new Date date
endDate.setHours 23, 59, 59, 59
options.date =
$lt: endDate
$gte: date
Meal.find options, (err, meals) ->
if err or not meals
handleError err, meals, res
else
res.json createJSON meals, null, 'meals'
i do it in this method and works fine
public async getDatabaseorderbyDate(req: Request, res: Response) {
const { dateQuery }: any = req.query
const date = new Date(dateQuery)
console.log(date)
const today = date.toLocaleDateString(`fr-CA`).split('/').join('-')
console.log(today)
const creationDate = {
"creationDate": {
'$gte': `${today}T00:00:00.000Z`,
'$lt': `${today}T23:59:59.999Z`
}
};

Problem I came into was filtering date in backend, when setting date to 0 hour, 0 minute, 0 second, 0 milisecond in node server it does in ISO time so current date 0 hour, 0 minute, 0 second, 0 milisecond of client may vary i.e. as a result which may gives a day after or before due to conversion of ISO time to local timezone
I fixed those by sending local time from client to server
// If client is from Asia/Kathmandu timezone it will zero time in that zone.
// Note ISODate time with zero time is not equal to above mention
const timeFromClient = new Date(new Date().setHours(0,0,0,0)).getTime()
And used this time to filter the documents by using this query
const getDateQuery = (filterBy, time) => {
const today = new Date(time);
const tomorrow = new Date(today.getDate() + 1);
switch(filterBy) {
case 'past':
return {
$exists: true,
$lt: today,
};
case 'present':
return {
$exists: true,
$gte: today,
$lt: tomorrow
};
case 'future':
return {
$exists: true,
$gte: tomorrow
};
default:
return {
$exists: true
};
};
};
const users = await UserModel.find({
expiryDate: getDateQuery('past', timeFromClient)
})
This can be done in another approach using aggregate if we have timezoneId like Asia/Kathmandu
const getDateQuery = (filterBy) => {
const today = new Date();
const tomorrow = new Date(today.getDate() + 1);
switch(filterBy) {
case 'past':
return {
$exists: true,
$lt: today,
};
case 'present':
return {
$exists: true,
$gte: today,
$lt: tomorrow
};
case 'future':
return {
$exists: true,
$gte: tomorrow
};
default:
return {
$exists: true
};
};
};
await UserModel.aggregate([
{
$addFields: {
expiryDateClientDate: {
$dateToParts: {
date: '$expiryDate',
timezone: 'Asia/Kathmandu'
}
}
},
},
{
$addFields: {
expiryDateClientDate: {
$dateFromParts: {
year: '$expiryDateClientDate.year',
month: '$expiryDateClientDate.month',
day: '$expiryDateClientDate.day'
}
}
},
},
{
$match: {
expiryDateClientDate: getDateQuery('past')
}
}
])
We had an issue relating to duplicated data in our database, with a date field having multiple values where we were meant to have 1. I thought I'd add the way we resolved the issue for reference.
We have a collection called "data" with a numeric "value" field and a date "date" field. We had a process which we thought was idempotent, but ended up adding 2 x values per day on second run:
{ "_id" : "1", "type":"x", "value":1.23, date : ISODate("2013-05-21T08:00:00Z")}
{ "_id" : "2", "type":"x", "value":1.23, date : ISODate("2013-05-21T17:00:00Z")}
We only need 1 of the 2 records, so had to resort the javascript to clean up the db. Our initial approach was going to be to iterate through the results and remove any field with a time of between 6am and 11am (all duplicates were in the morning), but during implementation, made a change. Here's the script used to fix it:
var data = db.data.find({"type" : "x"})
var found = [];
while (data.hasNext()){
var datum = data.next();
var rdate = datum.date;
// instead of the next set of conditions, we could have just used rdate.getHour() and checked if it was in the morning, but this approach was slightly better...
if (typeof found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()] !== "undefined") {
if (datum.value != found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()]) {
print("DISCREPENCY!!!: " + datum._id + " for date " + datum.date);
}
else {
print("Removing " + datum._id);
db.data.remove({ "_id": datum._id});
}
}
else {
found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()] = datum.value;
}
}
and then ran it with mongo thedatabase fixer_script.js
Well a very simple solution to this is given below
const start = new Date(2020-04-01);
start.setHours(0, 0, 0, 0);
const end = new Date(2021-04-01);
end.setHours(23, 59, 59, 999);
queryFilter.created_at={
$gte:start,
$lte:end
}
YourModel.find(queryFilter)
So, the above code simply finds the records from the given start date to the given end date.
Seemed like none of the answers worked for me. Although someone mentioned a little hint, I managed to make it work with this code below.
let endDate = startingDate
endDate = endDate + 'T23:59:59';
Model.find({dateCreated: {$gte: startingDate, $lte: endDate}})
startingDate will be the specific date you want to query with.
I preferred this solution to avoid installing moment and just to pass the startingDate like "2021-04-01" in postman.
