Is there truly a “best day to launch”?

Most of us launching soon come across lots of articles with titles like “Best Day To Launch on PH 2025” — not to mention the enormous amount of spam emails that offer to scale and optimise your launch. I wouldn’t say there’s such thing as a great or nearly-perfect day to launch, but rather just launch your product whenever you feel ready to do so. What are your thoughts on this? Have you also received some of this spammy emails? 😂
