…ythonGH-124946) In some locales (like French or Hebrew) the full or abbreviated names of the default month and weekday used in __calc_date_time can be part of other name or constant part of the %c format. The month name can also match %m with constant suffix (like in Japanese). So the code failed to correctly distinguish formats %a, %A, %b, %B and %m. Cycle all month and all days of the week to find the variable part and distinguish %a from %A and %b from %B or %m. Fixed locales for the following languges: Arabic, Bislama, Breton, Bodo, Kashubian, Chuvash, Estonian, French, Irish, Ge'ez, Gurajati, Manx Gaelic, Hebrew, Hindi, Chhattisgarhi, Haitian Kreyol, Japanese, Kannada, Korean, Marathi, Malay, Norwegian, Nynorsk, Punjabi, Rajasthani, Tok Pisin, Yoruba, Yue Chinese, Yau/Nungon and Chinese.
