How to pass value from an attribute to another attribute of the same collection?

I have this extended attributes for my 'Jobs' collection:

   var job = _.extend(jobAttributes, {
      userId: user._id, 
      author: user.profile.name.toLowerCase(),
      submitted: new Date(),
      commentsCount: 0,
      upvoters: [],
      votes: 10,
      apply: 0,
      tweets: 0,
      views: 0,
      day1: 2,
      day2: 0
    });

What I'm trying to do is send the value from 'Day1' to 'Day2'

I made a 'SyncedCron' for this

SyncedCron.add({
name: 'Update Example',
schedule: function(parser) {
    return parser.text('every 2 minutes');
},
job: function() {
    var one = this.day1;
    Jobs.update({'day2': one});
}
});

But instead of updating the attribute, I got this error:

Error: Invalid modifier. Modifier must be an object.

I use something like this to populate field based on another field while insert itself. I have defined schema such as..

Jobs = new Mongo.Collection("jobs");

Jobs.schema = new SimpleSchema({
  day1: {
    type: SimpleSchema.Integer,
  },
  day2: {
    type: Number,
    autoValue: function() {
      if (this.isInsert) {
        return this.siblingField("day1").value;
      }
    }
  }
});

Jobs.attachSchema(Jobs.schema);

The problem is with Jobs.update({'day2': one});.

From documentation:

collection.update(selector, modifier, [options], [callback])

selector and modifier has to be provided.
