+# Schedule Sidekiq Jobs Out Into The Future
+
+The most common way to schedule a [Sidekiq](https://github.com/mperham/sidekiq)
+job is with the `perform_async` method. That will queue up your job so that it
+is worked as soon as possible.  That may not also be desired. Sometimes you
+want a bit more say in when jobs are run.
+
+The `perform_in` and `perform_at` methods can help with scheduling jobs out
+into the future.
+
+With `perform_in` we can say how much time from now would be the soonest that
+we'd like the job performed.
+
+```ruby
+MyWorker.perform_in(10.minutes, arg1, arg2)
+```
+
+We can do the same thing with `perform_at`.
+
+```ruby
+MyWorker.perform_at(10.minutes.from_now, arg1, arg2)
+```
+
+Or we can schedule something out for a specific point in time in the future.
+
+```ruby
+MyWorker.perform_at(Date.today.end_of_week, arg1, arg2)
+```
