You can use toDateString() to better format date in JavaScript :

<% data.forEach(function(user){ %>
    <tr>
        <td>
            <%= user.date.toDateString() %>
        </td>
    </tr>
<% }) %>

If you want to display date in a custom format, you can use third party module like Moment.js. Using Moment.js your code would be like following:

app.js

var moment = require('moment');
app.get('/user.html', function(req, res){
    dbConnect.collection("users").find().toArray(function(err, docsData) {
        res.render('user', {
            data: docsData,
            title: "EJS example",
            header: "Some users",
            moment: moment
        });
    });
}); 

user.html

<% data.forEach(function(user){ %>
    <tr>
        <td>
            <%= moment(user.date).format( 'MMM-DD-YYYY') %>
       </td>
    </tr>
<% }) %> 

Hope this help!
