How to combine (join) two sketches

Greetings everyone
I have a code (Backlit_Automated_Perpetual_Calendar) that I got from a colleague on the internet, made for a Perpetual Calendar with LED strips and I would like to combine it with another code (TM1637_7Segment_Display_NTP_Clock) made for a Clock with the TM1637 Module. I've tried to combine but it didn't work. I was embarrassed because the first code uses the NTP.h library and has the header #ifndef NTP_H and #define NTP_H. And the second code uses the NTPClient.h library, so I would like someone to help, please.

Note 1: I note here that both codes were made for ESP8266.
Note 2: NTP.h belongs to the first code.

Forgive my English, as it is not my native language.

Hi Peter!
First, thanks for the tutorial link and for trying to help me.
I even managed to understand how the principle of the union of sketches works, but, as I said, one sketch uses the NTP.h library and the other uses the NTPClient.h library, so I think that is where it is showing some errors, maybe functions? !
I will make a few more attempts, however, if someone else can help me, I thank you all.

Someone else to help me?
If there is no solution, I will have to use two boards: esp8266 to manage the Calendar + Arduino Nano or Mini with RTC Module to manage the Clock, although the space is small.
I've tried in several ways, but I couldn't; my experience is little!
