    Hi Ed and sorry for the late answering.
    Thanks for you valuable advices. I will defenetely try the approaches you mentioned. Actully if I use RTC I will have really accure Clock and it is somehow obvious. In this project I tried to write a program without RTC module. But the approache that you said to make a change in programming method I will apply definitely. I am busy these days with my master thesis because of that I have to postpone this changes to later ;)
    Best regards

    Hi Ed and thank you for your comment.
    - About accuracy, I should say that unfortunately it is not so accure. I let it run about 3 days and I realized that it's about two minutes behind the actual time. So I would suggest not to use as a real clock ;). I made it like that because I didn't have any RTC at that time :D.
    - About second question, you are right, I think I made a mistake by making this diagram. Thanks for the attention and thanks that you mentioned it to me. I appreciate it. It is pullup so ground should be connected when we pree the button not +5V.
    - Actually I don't have any idea about it :D It works for me like that, or maybe my LCD has 5V incandescent, I have to check.

    Again thanks for your attention :) I will update the diagram as soon as possible and I have a RTC now and I will try to catch some free time to make a real clock with RTC.

    Best wishes

    It should work properly. What shows it on the LCD after 1 day?
