app.get('/reset/days', function(req, res){
  serviceDays = days.slice(0);
  res.json(serviceDays);
});
app.post('/remove/day', function(req, res){
  if (serviceDays.length > 2){
    serviceDays.splice(serviceDays.indexOf(req.body.day), 1);
    console.log(days);
    res.json(serviceDays);
  }else {
    res.json(400, {msg:'You must leave 2 days'});
  }
});
app.listen(8081);

which error you get? that's a key information to understand what you are doing wrong... — Paolo, Feb 09 '16 at 15:33
Might want to look this over. http://expressjs.com/en/guide/routing.html Usually you get that error because of an incorrect route. — khollenbeck, Feb 09 '16 at 15:33
Also just to be sure.. Can you post the URL that you are trying to go to? — khollenbeck, Feb 09 '16 at 15:34

I don't see you doing a .get() for this path /, which is the same as localhost:8081. Try doing something like this in your code.

app.get('/', function(req, res){
  serviceDays = days.slice(0);
  res.json(serviceDays);
});

This is the same as what you have here

app.get('/reset/days', function(req, res){
  serviceDays = days.slice(0);
  res.json(serviceDays);
});

So if you go to localhost:8081 or localhost:8081/reset/days, you should get the same result. What the message cannot GET / is saying is that there is no route set up for the requested url.

Also note: It looks like you are using app.use('/', express.static('./static')) in your code. But it looks like this is just defining all of your static routes for "static", "images", and "lib".

Here is some more info on .use vs .get
