Mine is also like that. The date format is one of the things you can change by modifying the home menu strings, you just need to edit the hud strings and reorder the month, day, and day name variables, in theory at least; I have looked at the file but not actually changed it.
I've been meaning to make a few more changes to my home menu so I'll try out changing it to Canadian DD/MM format.
Also, it's possible to change the positions of things on the home menu, however the person who found the offsets refused to disclose them.
Modifying the home menu is generally safe if you only change strings, modifying colours poses a brick risk if you get the offset wrong and don't notice. Of course with A9LH you can just restore a SysNAND backup if you screw up.
