title: Mongoose get all documents where date and number of weeks have current date
body: <p>I have this type of documents in mongoDB.</p>
  <pre><code>{

  }
  </code></pre>
  <p>Here I have &quot;start_date&quot; which is starting day. &quot;type_quantity&quot; which is number of weeks from start day.</p>
  <p><strong>Example:</strong> If &quot;start_date&quot; is 2022-02-17T00:00:00.000+00:00 and &quot;type_quantity&quot; is 2. Then, the dates per week will become 2022-02-17, 2022-02-24 and 2022-03-03. And If current date is one of these dates then, get this document.</p>
