mongodbHow to filter by date in MongoDB?

MongoDB provides a range of operators to filter documents by date. The most commonly used operators are $gt (greater than), $gte (greater than or equal to), $lt (less than) and $lte (less than or equal to).

For example, to filter documents with a date field createdAt greater than a given date, the following code can be used:

db.collection.find({
  createdAt: {
    $gt: new Date("2020-01-01")
  }
})

This will return all documents with a createdAt field greater than 2020-01-01.
