| mmm | Month as a three-letter abbreviation (Jan through Dec) | 
| yy | Year as a two-digit number (00 through 99) | 
| yyyy | Year as a four-digit number (0001 through 9999) | 
| ww | Day of the week as a two-digit number (00 for Sunday, 01 for Monday, 02 for Tuesday … 06 for Saturday) | 
Any other characters in the formatting mask are reproduced literally in the result.
