Who can help me?
Please:
- don't make posts with a single sentence or word. Explain what you mean in a synthetic but clear way
- don't delete your posts (it's futile, they're still readable on edit history...) but just edit and change what you need
- Don't cross-post problems over multiple threads, that makes hard to follow and against forum rules.
And then
Ok sir
Are you kidding us, or are you so on your own?
I think he just wants to solve his problem as quickly as possible. But you have to be patient.
Good work takes time.
The PCF8563 uses a different I2C address (0x51) (find your RTC on this page:
And some examples for your RTC
9400? Really?
I'm sorry but this code looks like a "Frankenstein" with a lot of changes made by more than one person, at least one of them doesn't seem to be familiar enough with coding, so it isn't an easy task.
I think he's not using that library, I see an #include <PCF8563.h> when the library you linked requires "#include <I2C_RTC.h>".
So we actually don't know what library the OP is using (maybe this?), he just liked us a Mediafire file sharing header file, we don't know how the PCF8563 is connected (and if its interface is I2C), he haven't provided more information about its code (except posting just the code after we have explicitly requested), we don't know what is his programming skill level, replies with single sentences... It's a hard task for us to understando and try to give some help, we'd be happy to help others, but IMHO as this is not our (paid) job, a few answers could be given to him.

Other than what I said before, however, I think that, not knowing which library he was using, at least "year" should be 2023 not 23.
Then I don't get why when turned on he always sets the RTC a specific date, in this case January 1, 2023 at 12:00:00. Why need an RTC if the date/time will be always the same when starts?
And the "century" variable defined, set to zero (!), and never used, is also wonderful.
Ok, I'll stop now... 
Haha. Fair assessment, Docdoctor. This is a shopping list of devices to keep a body alive...
