What time of day or week is ideal for launching?

Saturday. The competition is lesser as far as my experience!

I know Monday and Tuesday is the most competitive.

I think it might be Thursday. Tuesday and Wednesday are most competitive while Friday and Weekend have less traffic.

I think Tuesday work well. People are settled into the week but not yet overwhelmed. That's when I usually see a lot of activity on launches.

I recommend Tuesday or Wednesday because as user activity is optimal, support team is fully available, and there's enough time to handle any technical issues.
