Pada .Net memiliki standard Date time format, dimana date time format tersebut dapat kita ubah ubah sesuka kita sesuai dengan kebutuhan, baik dikarenakan bentuk penulisan penanggalan yang berbeda beda.
| Pattern | Fungsi | Contoh |
| d | Short date Format | 5/19/1990 |
| D | Long date Format | Sunday, August 15,1990 |
| t | Short time Format | 3:33 PM |
| T | Long time Format | 3:30:00 PM |
| f | Full date/time format (short time) | Sunday, August 22,1990 |
| F | Full date/time format (long time) | Sunday, August 22,1990 3:30:00 PM |
| g | General date/time format (short time) | 3/30/1990 3:30 PM |
| G | General date/time format (long time) | 3/30/1990 3:30:00 PM |
| m or M | Month day format | August 30 |
| r or R | RFC 1123 | Sun, 30 Aug 1990 3:30:00 GMT |
| s | Sortable date /time format | 1990-08027T15:30:00 |
| u | Universable sortable date/time format | 1990-08-27 15:30:30:00z |
| U | Universable sortable date/time format | Sunday, August 30,1990 12:30:00 PM |
| y or Y | Year month format | August, 1990 |
