How to find date of end of week in Ruby?

Question

I have the following date object in Ruby ``` Date.new(2009, 11, 19) ``` How would I find the next Friday?

Accepted Answer

You could use end_of_week (AFAIK only available in Rails)

```
>> Date.new(2009, 11, 19).end_of_week - 2
=> Fri, 20 Nov 2009
```

But this might not work, depending what exactly you want. Another way could be to

```
>> d = Date.new(2009, 11, 19)
>> (d..(d+7)).find{|d| d.cwday == 5}
=> Fri, 20 Nov 2009
```

lets assume you want to have the next friday if d is already a friday:

```
>> d = Date.new(2009, 11, 20) # was friday
>> ((d+1)..(d+7)).find{|d| d.cwday == 5}
=> Fri, 27 Nov 2009
```
