Heeya Guys! Today I created a project with the help of instructables site. I followed the on screen steps and everything. Uploaded the sketch and it works like a charm, but there's one problem.
Everything works correctly but not the "Day", i.e as of today its Friday, 9 April 2021, the clock shows the correct time and date but it tells that today is "Tuesday" in place of Friday. I don't know why this is happening. Any help would be appreciated :) Here's the code that I'm using:
