I am just at your online demo of localization of the scheduler:
And chose language to zh-CN, all the text on the button in scheduler is translated into Chinese, but not the text on the head of the Month View.
They still show as Sunday, Monday and so on. Also, the datepicker on the scheduler is still in English too.
How to localize the month view's head and datepicker on the scheduler?
Please see the image I cut.
