Is there any possible way to find out the date when a microcontroller (pic series) was programmed?

No. Unless the original programmer encoded the date into the program memory or the EEROM data memory. It might not be the date it was programmed -- more likely it is the date the firmware was last compiled.

And I can see that date (which may be the date of programming) only if the microcontroller was not set to protect code, right?

Same as reading anything else - with the programmer. This assumes that the PIC device has EEPROM data memory, it is not secured, and the programmer can read it. Generally speaking there is nothing in EEPROM data memory that requires it to be secured.
