Let's get a date object containing the end of the current day:

```
let now = new Date();
let date = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 23, 59, 59);
```

You can consider the end of the current
day as midnight of the next (difference
is `1`

second):

```
let now = new Date();
let date = new Date(now.getFullYear(), now.getMonth(), now.getDate() + 1, 0, 0, 0);
```

As you already know, zeros can be omitted in this case:

```
let now = new Date();
let date = new Date(now.getFullYear(), now.getMonth(), now.getDate() + 1);
```

By the way, midnight will also be the time
`24`

:00:00 of the current day:

```
let now = new Date();
let date = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 24, 0, 0);
```

Omit the zeros:

```
let now = new Date();
let date = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 24);
```

Determine how many hours are left before the end of the day.
