| d | Short date pattern |
| D | Long date pattern |
| f | Full date and time (long date and short time) |
| F | Full date time pattern (long date and long time) |
| g | General (short date and short time) |
| G | General (short date and long time) |
| m, M | Month day pattern |
| r, R | RFC1123 pattern |
| s | Sortable date time pattern (based on ISO 8601) using local time |
| t | Short time pattern |
| T | Long time pattern |
| y | Month year pattern |
The table below shows a list of patterns that can be combined to create date format patterns.
The patterns are case-sensitive; for example, "MM" is recognized, but "mm" is not. If the date
format pattern contains white-space characters or characters enclosed in single quotation marks,
the formatted string will also contain those characters. Characters not defined as part of a
format pattern or as format characters are reproduced literally.

| d | The day of the month. Single-digit days have no leading zero. (Only if used in the context of a longer pattern. A single "d" on its own represents the Short date pattern.) |
