How to read and write dates when expressing in English?

English dates are divided into English and American, as follows:

8 February 20 12 or 8 February 20 12 (UK)

8 February 20 12 or 8 February 20 12 (USA)

note:

You can't write all Arabic numerals, otherwise it will cause misunderstanding.

The year must be fully stated.

The month must be spelled or abbreviated in English to be recognizable.

Dates can be expressed by ordinal numbers.

The year, month and day must be separated by commas.
