The answer would depend on what type of RTC you have.However, the Arduino Time library makes it easy to compare dates and times, and take action.
You can learn to use it without using an RTC (using the Arduino functions instead), and add the RTC later to keep accurate track of the time.
The RTC I have is a DS1307. How would i incorporate the time functions to run it during those times, and include the RTC after
