# Date Format Patterns

The table below shows a list of the standard format characters of the [ASP NET AJAX Calendar](https://www.telerik.com/products/aspnet-ajax/calendar.aspx) dates. For each standard pattern, it shows the pattern from the current [CultureInfo](https://www.telerik.com/products/aspnet-ajax/documentation/controls/calendar/accessibility-and-internationalization/specifying-a-culture) settings that the pattern represents. The format characters are case-sensitive, for example, 'f' and 'F' represent different patterns.

| Format Character | Description                                                     |

| 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                                               |

| s                | Sortable date time pattern (based on ISO 8601) using local time |
| t                | Short time pattern                                              |
| T                | Long time 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.

| Format Pattern | Description                                                                                                                                                                                                        |
