How to search date between two dates in MongoDB?

To search date between two dates in MongoDB, use $gte and $lt. Let us create a collection with documents −

> db.demo524.insertOne({"EndDate":new ISODate("2020-01-19")});{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e8adbe5437efc8605595b63")
}
> db.demo524.insertOne({"EndDate":new ISODate("2020-01-20")});{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e8adbec437efc8605595b64")
}
> db.demo524.insertOne({"EndDate":new ISODate("2020-12-31")});{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e8adbf3437efc8605595b65")
}

Display all documents from a collection with the help of find() method −

> db.demo524.find();

This will produce the following output −

{ "_id" : ObjectId("5e8adbe5437efc8605595b63"), "EndDate" : ISODate("2020-01-19T00:00:00Z") }
{ "_id" : ObjectId("5e8adbec437efc8605595b64"), "EndDate" : ISODate("2020-01-20T00:00:00Z") }
{ "_id" : ObjectId("5e8adbf3437efc8605595b65"), "EndDate" : ISODate("2020-12-31T00:00:00Z") }

Following is the query to search data between two dates in MongoDB −

> var first = new ISODate("2020-01-04");
> var last = new ISODate("2020-01-31");
> db.demo524.find({EndDate: {$gte: first, $lt: last}});

This will produce the following output −

{ "_id" : ObjectId("5e8adbe5437efc8605595b63"), "EndDate" : ISODate("2020-01-19T00:00:00Z") }
{ "_id" : ObjectId("5e8adbec437efc8605595b64"), "EndDate" : ISODate("2020-01-20T00:00:00Z") }
