How can I create a function that transforms dates into integer number?

For example, considering the format day/month/year:

I want the day 01/01/2020 to be considered number 1, day 02/01/2020 number 2 and so on...

When the month changes, I want to continue the count, so 01/02/2020 would be number 32 and not number 1 again.

This way I would create a function to use with pandas apply function to create a new variable.

Do you want to extract day from the date? – Dejene T. Jun 04 '21 at 17:35
I do not want the day of month. I added more info about what I expect when the month changes. – Matheus Nascimento Jun 04 '21 at 17:40
