How to Sort by Date in MongoDB?

In many applications, especially those dealing with time–series data or event logs, there is a common need to sort documents based on their date. For example, consider an application that tracks user activities such as logging in, making purchases or interacting with content. Being able to sort these activities can provide valuable output into user behavior over time. Below are the two methods in the MongoDB that allow to sort a collection by date are as follow:

1. Sort by Date Ascending
2. Sort by Date Descending

Let’s set up an environment to sort a collection by date in MongoDB.

To understand How to sort a collection by date in MongoDB we need a document on which we will perform various operations and queries. Here we will consider a collection of events that consists of the below records into it. So we have considered a collection named “events” containing documents with a “timestamp” field representing the date of the event.

db.events.insertOne({event: "Geeks Event 1", timestamp: new Date("2024-01-20")})
db.events.insertOne({event: "Geeks Event 2", timestamp: new Date("2024-01-21")})
db.events.insertOne({event: "Geeks Event 3", timestamp: new Date("2024-01-22")})
db.events.insertOne({event: "Geeks Event 4", timestamp: new Date("2024-01-23")})
db.events.insertOne({event: "Geeks Event 5", timestamp: new Date("2024-01-24")})

In MongoDB, sorting collections by date is a common requirement for many applications. Sorting by date allows us to display data in reverse order, making it easier for users to understand and analyze. In this article, we will explore different approaches to sorting collections by date in MongoDB, using various techniques and methods along with examples and so on.
