Be careful with the date. In Britain , they write the day first, but in the United states they write the month first. This means that
04.05.2004 in Britain will be understood as the fourth of May, while in US they will take it for April the fifth.
So write the date like this:
04 May 2006
And then everyone will know what you mean.
Remember to use a capital letter in the month.
Never in a letter (in the Date block, or in the Body) write th, nd, rd, or st after the day.
Never write dates like this 04/05/06
Always write the year in full (4 figures)
Remember that in Block style there is no punctuation in the date
