In MongoDB, `Date` objects are stored in [Unix timestamp](https://attacomsian.com/blog/unix-timestamp-javacript) format representing the number of milliseconds since the Unix epoch (Jan 1, 1970).

Let us say that we have the following `Task` model in Mongoose:

```javascript
const mongoose = require('mongoose')

const Task = mongoose.model('Task', { dueDate: Date })
```

To find all the tasks that belong to last month, you need to query for the start and end of the last month as shown below:

```javascript
const start = new Date(2022, 6, 1) // 1st July, 2022
const end = new Date(2022, 6, 31) // 31 July, 2022

const tasks = await Task.find({
  dueDate: {
    $gte: start,
    $lte: end
  }
})
```
 
`$gte` and `lte` are comparison operators in MongoDB to select documents where the field value is between specific values.
 
For more accurate start and end dates, I suggest to use the [date-fns](https://date-fns.org/) utility library instead:
 
```javascript
const { startOfDay, endOfDay } = require('date-fns')

const start = new Date(2022, 6, 1)
const end = new Date(2022, 6, 31)

const tasks = await Task.find({
  dueDate: {
    $gte: startOfDay(start),
    $lte: endOfDay(end)
  }
})
```
