I'm trying to set up an ID field that works like this for news articles

I know how to generate the date, and I am pretty sure I can generate the
letter code based on counting the number of rows and then assigning the
next letter (we will never have more than 26 in a day... usually its
closer to 1 or 2 per day).
The problem is if there has been something deleted.

If I then Count the rows with this date I get an answer of 2, and so the
next letter should be "c" but there already is a "c" because "b" got
deleted.
So, is there any way of generating this style ID number automatically?

Why not simply use the Unix time stamp. time() If more than one can arrive within the same second, append a letter.
If users need to see the key, use date() to decode it for them
