When learning Ruby on Rails, sometimes you just need to get the current year as a number. I posted one example on why this is a useful way on a real-life website in the 2011 post on how to automatically update copyright notices.

In this article, I will show you some methods for getting the current year, such as the number 2015. I will then show you how to benchmark the methods to determine which is the fastest method for you, given your machine and Ruby version.

Okay, just how do I get the Current Year in Ruby?

It’s easy. Just use any of the Date/Time objects and call the year method, like this:

   # Using the Time class
   current_year = Time.new.year  # or Time.now.year

   # Using the Date class
   current_year = Date.today.year

   # Using the DateTime class
   current_year = DateTime.now.year
