 - Year: The count of letters determines the minimum field width below which padding is used. If the count of letters is two, then a reduced two digit form is used. For printing, this outputs the rightmost two digits. For parsing, this will parse using the base value of 2000, resulting in a year within the range 2000 to 2099 inclusive. If the count of letters is less than four (but not two), then the sign is only output for negative years. Otherwise, the sign is output if the pad width is exceeded when 'G' is not present.
 
-- Month: If the number of pattern letters is 3 or more, the month is interpreted as text; otherwise, it is interpreted as a number. The text form is depend on letters - 'M' denotes the 'standard' form, and 'L' is for 'stand-alone' form. The difference between the 'standard' and 'stand-alone' forms is trickier to describe as there is no difference in English. However, in other languages there is a difference in the word used when the text is used alone, as opposed to in a complete date. For example, the word used for a month when used alone in a date picker is different to the word used for month in association with a day and year in a date. In Russian, 'Июль' is the stand-alone form of July, and 'Июля' is the standard form. Here are examples for all supported pattern letters (more than 4 letters is invalid):
+- Month: It follows the rule of Number/Text. The text form is depend on letters - 'M' denotes the 'standard' form, and 'L' is for 'stand-alone' form. These two forms are different only in some certain languages. For example, in Russian, 'Июль' is the stand-alone form of July, and 'Июля' is the standard form. Here are examples for all supported pattern letters:
   - `'M'` or `'L'`: Month number in a year starting from 1. There is no difference between 'M' and 'L'. Month from 1 to 9 are printed without padding.
