What are the best days to launch on product hunt?

If the market demand for a new product is highly seasonal, the new product should be put on the market when the sales season comes; If this new product can still be improved, it is not necessary to rush to the market, but should wait until it is perfect before putting it on the market.

I've heard Thursdays are good, weekends are not that great 🙌

Any day, once you have completed the preparation, is suitable. Weekdays generally get high competition and chances of getting more traction for your product. But, if you only want the product of the day title, then the weekend is perfect.
