I recently asked https://superuser.com/questions/650929/tool-software-to-surprise-during-birthday on Super User. Will the question would be off topic? I have mentioned my problem clear. Normal search on search engines doesn't helped me, so posted as an question over here.
Will the question would be off topic?
Yes, your question is off-topic. The reason why it is off-topic is displayed below your question.
In cases like these, it would make sense to edit your question to make it less about a simple product recommendation and more about the process of achieving your goal.
A better question to ask would be How can I trigger a certain program when the computer starts up on a given date? Which is essentially what you want to do.
You should tag your question with osx and windows to make it clear that you want to learn about the process for both operating systems.
