When I create a new document with the aforementioned schema the date that is placed in the database is always the same and corresponds to the start time of the current process. It feels like when indexed the now function is called when the schema is created and reused for every newly created documents.

Mongoose schemas support a timestamps option. If you set timestamps: true , Mongoose will add two properties of type Date to your schema:. Mongoose will then set createdAt when the document is first inserted, and update updatedAt whenever you update the document using save , updateOne , updateMany , findOneAndUpdate , update , replaceOne , or bulkWrite. The createdAt property is immutable, and Mongoose overwrites any user-specified updates to updatedAt by default. For the purposes of these docs, we'll always refer to createdAt and updatedAt. But you can overwrite these property names as shown below. Set timestamps: false to skip setting timestamps for that particular operation. You can also set the timestamps option to an object to configure createdAt and updatedAt separately. For example, in the below code, Mongoose sets createdAt on save but skips updatedAt. Disabling timestamps also lets you set timestamps yourself. For example, suppose you need to correct a document's createdAt or updatedAt property. You can do that by setting timestamps: false and setting createdAt yourself as shown below. Mongoose also supports setting timestamps on subdocuments.

I'll deal with this issue on the frontend; sorry for the bother! MongoDB supports querying by date ranges and sorting by dates. Skip to content.

When you create a user document , Mongoose will cast the value to a native JavaScript date using the Date constructor. An invalid date will lead to a CastError when you validate the document. Dates have two built-in validators: min and max. These validators will report a ValidatorError if the given date is strictly less than min or strictly greater than max. MongoDB supports querying by date ranges and sorting by dates. Here's some examples of querying by dates, date ranges, and sorting by date:.

Managing dates and times is an essential aspect of data modeling in any database system. In MongoDB, date formatting and manipulation can be both versatile and complex. From the simplest usage of Date fields to more advanced techniques such as querying and indexing date fields, you will come away with a robust understanding of handling datetime in Mongoose effectively. Mongoose serves as a powerful bridge between MongoDB and the Node. It becomes especially important to consider this behavior when working across different time zones and storing data that needs a standardized format, such as UTC. To maximize the functionality and avoid common pitfalls with Date types in Mongoose, your schemas need to be defined accurately, and operations regarding dates—such as sorting, formatting, and querying—need to be handled with care. However, often applications need to automatically record the creation and modification times of a document. In such cases, Mongoose provides a shortcut:. With the timestamps option enabled, Mongoose automatically adds createdAt and updatedAt fields to your schema, and manages those fields for you.

Mongoose schemas have a timestamps option that tells Mongoose to automatically manage createdAt and updatedAt properties on your documents. For example, here's how you can enable timestamps on a User model. When you enable timestamps, Mongoose adds createdAt and updatedAt properties to your schema.

Returns a date either as a string or as a Date object. The date can contain a date and a time, known as a datetime. The UTC datetime stores an unsigned bit integer value, indicating the number of milliseconds after the Unix epoch January 1st, at UTC.
