Request for API for 'next business Friday' etc

[nzifnab]

I've come across a situation where I'd like to have a date for "The friday that follows X". So if "X" is a tuesday, I want it to be the following friday, if X is a friday, it can return X. Similar to how first_business_day will return the given day if it is a business day, otherwise the next one. If the immediately following friday isn't a workday it can return the one after that. If you've done something impossible like chosen :saturday, and no Saturdays can be work days... maybe raise an error, or return nil.

I would propose perhaps just an additional param in first_business_day, something like:

Time.first_business_day(Time.current, :friday)

Or:

Time.first_business_day(Time.current, day_of_week: :friday)

Update:

FWIW I'm just going to do it this way for now, which is "good enough" for my use-case I think:

Time.current + ((5.days-Date.current.wday.days) % 7.days)
