To query data on a weekly basis in MongoDB, you can use the aggregation framework to group and count data based on the week.


Here is an example of how you can query data on a weekly basis in MongoDB:

db.collection.aggregate([
  {
    $project: {
      week: { $week: "$dateField" }, // You can replace "dateField" with the field in your collection that contains the date
      data: 1
    }
  },
  {
    $group: {
      _id: "$week",
      count: { $sum: 1 }
    }
  },
  {
    $sort: { _id: 1 }
  }
])


In the above example:

  • Replace "collection" with the name of your collection.
  • Replace "dateField" with the field in your collection that contains the date.
  • The $week operator extracts the week number from the specified date field.
  • The $project stage projects the week number and other fields that you want to include in the output.
  • The $group stage groups the data based on the week number and counts the documents in each group.
  • The $sort stage sorts the results in ascending order based on the week number.


This query will return the count of documents for each week in your collection. You can further customize the query based on your specific requirements.
