Joanna (Asia) Name days?

I sent regards to an old friend after seeing that today, 24/08 was her name day at the bottom of the page on this Forum! Oops! I checked on Google and maybe it should have been 24/05. Can anyone help on this. Her name is Joanna (Asia)! I think I dropped a Boo-Boo.

Do you know when she was born? Because in Poland it's usually the first name day in the calendar after the birthday (Joanna has at least 21 name days in the calendar according to Wikipedia ;)).

It wasn't today. My calendar lists Jerzego and Bart£omieja as having name days today. Oh well.

I have two questions about Polish...
how can a girl named Joanna, her nickname would be Asia? -_-"
I've heard a few other names that the nickname has no resemblence with the original name.
In English, it's pretty easy, Robert is Rob or Bob, Joanna is Anna or Jo, etc. even in Arabic the nickname is always derived from the name itself.

Can somebody explain the logic behind a nickname such as Asia? I'm not making fun of it or being sarcastic, I am sincerely curious to understand the culture behind such a thing :)

My second question is, the names order. In Arabic, we use this order = Given name + father's name + family name with bin or ibn between each name (meaning, son of). for Example, the king of Saudi Arabia is Abdullah ibn Abdulaziz Al-Saud.

What's the naming system in Poland? Do you use middle name like they do in USA? How does the name

Asia is short for Joasia which definitely is derived from Joanna. English also has hypocoristic forms that at first glance may not seem related to the original: eg: Peggy < Margaret, Bill < WIlliam, Ned < Edward.

The order is:
first name + (optionally) second name + surname. Not everyone has second name. No tradition of including father's name. Some surnames change gender if carried by a woman (from -ski to -ska).

There is also an oldfashioned tradition to add other kind suffixes to women surnames which reflect if she's a Miss or Mrs, but you won't find it in official documents:

Mr Kowal has wife called Mrs Kowalowa while their daughter is called Miss Kowalówna. However I will stress that again: it's oldfashioned now and only elders refer like that.

@polonius:
Thanks LOADS! It was killing me trying to figure it out xD and you do have a point about English, I have no idea why Peggy & Bill didn't come to my mind :P

@zetigrek:
That was very informative, and cleared out a lot of things :) Thank you very very very much

I have a similar query, I don't really know her date of birth, but could you kindly explain how the system works. I appreciate your help. Thank you. We normally call her Aska and her actual name is (Joanna). I would be thankful if you can tell me what would be her name day.....

next Joanna name day follows on: 17 Aug, 21 Aug, 24 Aug, 26 Aug , 9 November.
Pick up one and celebrate, she would likely tell you if the date isn't right and WHEN is her name day celebration day - happens all the time at workplace. If she does celebrate her day she will bring some sweets and alcohol to share.
