An Academic Look at Bday

Bday is a shortened version of the word "birthday," therefore it is a contraction. Contractions can be formed in a number of ways, including:

Omitting letters from the word (e.g., bday, pct (percent), obv (obviously)).
Using letters from the start and end of the word (e.g., adds, Dr (Doctor)).
Using an apostrophe to replace a letter or letters (e.g., don't (do not), can't (cannot)).

For reasons of brevity in text-based conversations, contractions are rarely followed by periods/full stops and apostrophes are routinely omitted.
