Rails-ier way to get hours in a day?

I needed to know how many hours were in a Daylight Savings Day and ended up with this:

>(Time.zone.parse('31-10-2021').end_of_day - Time.zone.parse('31-10-2021').beginning_of_day)/3600
=> 24.99999999999972

Is there a Rails-ier way? something like Date.parse('31-10-2021').hours or Date.parse('31-10-2021').hours_in_day ?

If you're using Rails 6.1 you can use ActiveSupport::Duration#in_hours:

hours = Time.zone.new(2021, 10, 31).then do |day|
  (day.beginning_of_day-day.end_of_day).in_hours
                                       .round.to_i # optional 
end

In older versions of Rails you can do:

hours = Time.zone.new(2021, 10, 31).then do |day|
  ((day.beginning_of_day-day.end_of_day) / 1.hour).round.to_i
end
