Writing the Date
There are several different ways to write the date in English. They vary from formal to informal, and there are differences between British and American English. The following table shows some typical formats.
| Format |
British: Day-Month-Year |
American: Month-Day-Year |
| A |
the Fourteenth of March, 1999 |
March the Fourteenth, 1999 |
| B |
14th March 1999 |
March 14th, 1999 |
| C |
14 March 1999 |
March 14, 1999 |
| D |
14/3/1999 |
3/14/1999 |
| E |
14/3/99 |
3/14/99 |
| F |
14/03/99 |
03/14/99 |
Note: which format to use is a question of formality, politeness and personal choice. Generally, the longer formats, such as B or C, are more polite (since they show more respect for the reader). Shorter formats, such as D or E, are used in less formal situations, for example a memo, a letter between friends or an impersonal business letter. Format F is rather official and is typically seen on an invoice or an official or technical document. Format A is extremely formal and mainly used on printed items, for example a wedding invitation. The numerical formats may use a full stop (.) or hyphen (-) instead of a slash (/), for example: 14.3.1999 or 03-14-99
