Which day, date of the month, month is the most profitable?

Most traders tend to say; If something works in the past market, then it would work in the future. If this statement is true, then why don't just trade in a profitable day, date, and time? I wouldn't follow this kind of trade, at least for now. haha

Komen:

The Data is based on my Data Analysis, where I check specific days, weeks, month, and dates of the month. On that specific date, I will check how many Change Rate the price changed compared to yesterday's date. Then I will SUM all the numbers collected in the data to form a "profitable" date.

in the bright side, I believe that there is some influencer/whale in Cardano that are active in certain dates and time which would explain all of this things.
