Follow these steps:
- Create a new calendar.
Don't worry that the created calendar has months, days and days of the week in your current configured language; that will get fixed in the last step. - Select and arrange your photos to your liking. If you input text, enter it in the language with which you want to publish your calendar. That won't change no matter what your language setting.
- Save one last picture to add or remove from your calendar. That's the trick--you have to perform an edit to have the calendar change to the newly configured language.
- Configure both the Language and Formats to the language you want to use to publish your calendar.
In my example, I'm changing the language to Chinese:
And the Formats from United States to China: - Quit iPhoto.
- Open iPhoto.
- Make one last edit to your calendar.
The calendar should now be displayed in the newly configured language.
And as long as you don't make any edits, it should stick, even after you change back to your original configured language. - Purchase calendar. Note: I'm leaving OS X in the target language when purchasing the calendar, to make sure that purchasing doesn't cause a change back to the original language. I'll update this blog when I receive my calendar in Chinese...
Update: Success! My calendar was delivered, and the dates are in Chinese. Note that when I purchased the calendar, I left the OS X language configuration in Chinese, so I didn't take any chances. I believe that once you see the calendar uploaded, and it's still in your target language, you're all set.
