<p>Here's a simple (hopefully) L10N question:</p>

<p>Do all locales want this format: </p>

<p><em>Sunday, Nov 23, 2008</em></p>

<p>with the weekday before the date, or do some locales want it after the date like this?</p>

<p><em>Nov 23, 2008, Sunday</em></p>

I can't answer for all locales, but in French, we say "dimanche 23 novembre 2008", so for us, the answer is yes.
Now, I don't know your purpose, but you probably shouldn't make any guess like that anyway...
[EDIT] Funnily, I found an example in analyzing how the zh_TW locale is setting the date/time formats in Java 1.4. I found the format for this locale to be (after decompiling it):
```
```
"ahh'\u6642'mm'\u5206'ss'\u79D2' z", 
"ahh'\u6642'mm'\u5206'ss'\u79D2'", 
"a hh:mm:ss", 
"a h:mm", 
"yyyy'\u5E74'M'\u6708'd'\u65E5' EEEE", 
"yyyy'\u5E74'M'\u6708'd'\u65E5'", 
"yyyy/M/d", 
"yyyy/M/d", 
"{1} {0}"
```
```
while default, for US (found on the Net), is:
```
```
"h:mm:ss a z", // full time pattern
"h:mm:ss a z", // long time pattern
"h:mm:ss a", // medium time pattern
"h:mm a", // short time pattern
"EEEE, MMMM d, yyyy", // full date pattern
"MMMM d, yyyy", // long date pattern
"MMM d, yyyy", // medium date pattern
"M/d/yy", // short date pattern
"{1} {0}" // date-time pattern
```
```
See the full date pattern, the EEEE (day in week) is at the end for Taiwan...
