## Dr Strange

### Instructions

You will create two functions: `addWeek` and `timeTravel`.

You have been given a mission to create a new sense of time. Normally a week has 7 days right? Well, that is about to change.

Days will instead have **14** days.

Let me explain; this new week will have 14 days, from `Monday` to `Sunday`, then `secondMonday` to `secondSunday`.

Your purpose is to create a new function named `addWeek`, that takes a `Date` as an argument. Your function should return the weekday as a string, according to our new 14-day week format.
The **epoch** of our new 14-day week is `0001-01-01`, and that was a `Monday`.
> What is an epoch?

Now imagine you have an appointment with your doctor, and you have to wait for some hours, but you do not want to wait. So you decide that you need to create a new function named `timeTravel`, that allows you to change the **time** according to your needs.

Your function will take an `object` as an argument, and return a `Date`. You can see the `timeTravel` example below to understand the structure of the `object` argument.

Your objective is to use the information from the `object` to modify the **time** of the `Date` before returning it.

### Example

```js
addWeek(new Date('0001-01-01')) // Output: Monday
addWeek(new Date('0001-01-02')) // Output: Tuesday
addWeek(new Date('0001-01-07')) // Output: Sunday
addWeek(new Date('0001-01-08')) // Output: secondMonday
addWeek(new Date('0001-01-09')) // Output: secondTuesday

// timeTravel({ date, hour, minute, second })

timeTravel({
  date: new Date('2020-05-29 23:25:22'),
  hour: 21,
  minute: 22,
  second: 22,
}).toString()

// Output: Fri May 29 2020 21:22:22 GMT+0100 (Western European Summer Time)
```
