On Facebook, on the homepage, it tells you whos birthday it is today. For the past 20 hours, I've seen the same name up and it felt like it was that person's birthday for the past 3 days. So I say : How long is it your birthday? [being sarcastic]
How long is it your birthday? Is that something you could say in that context? Is the question asked correctly?
Regards
