DS1302 to DS3231 conversion

I found @JR_ECT's Video on YouTube, and It is perfect for me to edit a little for my own project. @pert helped me figure out the first error with the LCD, so now I want to attempt to tackle something else. @JR_ECT used a DS1302 RTC, but I want to use a DS3231 RTC. How can I convert the code for the DS3231? Thank you, and your time is greatly appreciated.

There are libraries that support the DS3231 RTC.
