rails:whenever gem:run job every year

Question

How can I write cronjob using whenever gem in rails 4.0 for last day of every year or any specific day of every year.

for ex. 31st dec, 11:59 pm of every year or 15th july of every year.

i am trying this,

every 1.year do
  rake "namespace:jobname"
end

but where to mention day and time?

Please help, Thanks in advance.

For 31st dec, 11:59 pm,try this

every 1.year, :at => 'December 31th 11:59pm' do
  rake "namespace:jobname"
end

For 15th july,try this

every 1.year, :at => 'July 15th' do
  rake "namespace:jobname"
end

OR

every '0 0 15 7 *' do
  rake "namespace:jobname"
end
