Whenever gem how to work on windows system?

Question

Gemfile

gem 'whenever', '~> 0.9.4',:require => false  

config/schedule.rb

 runner "DailyAttendance.fetch_data"
end

Answer 1

Cron is a linux application and does not exist on Windows.

Whenever gem does not schedule tasks on it's own, all it does it convert the cron syntax into a human readable form and supply it to the crontab.
