Here is the situation in detail - I was working in this Organization X when I got an offer from other Organization Y. The joining for Organization Y was in 45 days but the notice period for Organization X was 2 months. Here is where things get complex. I put my papers and asked my manager (X Firm) to release me early, to which he agreed initially; as a result I completed formalities for Y firm. After a month, the Manager denied to release me and asked to serve full notice period, which I couldn't as I had to join Y in 15 days. I anyhow worked for 15 days after which I left X and joined Y, post which I had a word with HR of X and got my experience letter. The issue is that in my offer letter from Y, joining date in 15th of May, however in my experience letter, my Last Working Day is reflected as 31st May (2 months of notice period). I am concerned about how should I explain this to any future organizations. Will they listen to me? Will this pose a problem in Background Verification?

I anyhow worked for the extra 15 days after which I left X and joined Y, post which I had a word with HR of X and got my experience letter.
