Question

How do I check how many days left until a specific date?

For example, I want to start executing some logic after 3 days from today? I will be hard coding today’s date, and subtract now from it, but how?

EDIT

What I want to do is to disable devise confirmation email at model for the next three days,

if Rails.env== 'production' && (three days left sense 1/7/2013)
   devise :confirmable
end

Answer 1

why bother?

if Rails.env== 'production' && Time.now.strftime("%Y%m%d").to_i >= 20130110
    devise :confirmable 
end
