How can I get the cookie expiration for 'connect.sid' on client-side?

My web application is using AngularJS, NodeJS, Express, and Passport. When I do a CTRL+Shift+I and look at the Cookies under the Resources tab on Google Chrome, I see 'connect.sid' that I would like get the expiration date from. Is it possible? I have tried using document.cookie on the client-side but nothing shows up.

This is the code I used to set up the expiration date for 'connect.sid'

 app.use(express.session({cookie : { maxAge: 3600000 * 24 * 30 * 2 }));
