please forgive me my bad english ;-)

i try to find out where the localized strings for the days of the apple iphone calendar app are stored.

the days are shown on the calendar icon at the springboard in addiction of the selected language.

for example in german is displayed 'Montag' instead of the english Monday.

but i can not find any .strings file where these strings are defined.
not in MobileCal.app (German.lproj), not in Calendar.framework, not in MobileCalSettings.bundle ...

can anyone help me please?

thank you.
