Arduino doesn’t have built-in date and time functions, but you can use the “TimeLib.h” library to handle date calculations.
In Arduino, you can compare dates using the TimeLib.h library.
TimeLib.h
Here’s a straightforward example of converting a date to a string on Arduino.
Arduino itself doesn’t have a built-in method to directly fetch the current date, as it lacks a real-time clock (RTC).
Direct approach without a third-party library.
