title: How to specify date as a data type in json
body: <p>I'm building a parquet converter in python that takes in a json with the fields and the dtypes of those fields. How do I classify a field that has a data type as <code>date</code> in a json?</p>
  <pre><code>{
    &quot;contact_firstname&quot;: &quot;string&quot;,
    &quot;contact_suffix&quot;: &quot;string&quot;,
    &quot;contact_middle_name&quot;: &quot;string&quot;,
    &quot;contact_email_address&quot;: &quot;string&quot;,
    &quot;contact_date_of_birth&quot;: &quot;datetime&quot;,
    &quot;contact_address_line_2&quot;: &quot;string&quot;,
    &quot;contact_address_line_3&quot;: &quot;string&quot;
  }
  </code></pre>
