-# Useful ActiveSupport Constants For Durations
-
-Whenever I'm passing a duration to a function, I like to [name it with the
-unit](https://ruudvanasseldonk.com/2022/03/20/please-put-units-in-names)
-relative to the value it represents. For instance, if I need to pass in an hour
-duration in seconds, I might write the following line:
-
-```ruby
-hour_in_seconds = 60 * 60
-
-# or
-
-hour_in_seconds = 3600
-```
-
-ActiveSupport has a [Duration
-class](https://api.rubyonrails.org/classes/ActiveSupport/Duration.html) with a
-series of constants that we can reach for.
-
-```ruby
-> ActiveSupport::Duration::SECONDS_PER_MINUTE
-=> 60
-> ActiveSupport::Duration::SECONDS_PER_HOUR
-=> 3600
-> ActiveSupport::Duration::SECONDS_PER_DAY
-=> 86400
-> ActiveSupport::Duration::SECONDS_PER_WEEK
-=> 604800
-> ActiveSupport::Duration::SECONDS_PER_MONTH
-=> 2629746
-> ActiveSupport::Duration::SECONDS_PER_YEAR
-=> 31556952
-```
-
-Though it is fun to know about these, we should keep in mind that this class
-provides support for what is likely to be a more useful abstraction layer:
-
-```ruby
-> 1.hour
-=> 1 hour
-> 3.hours
-=> 3 hours
-> 1.day.to_i
-=> 86400
-```
