On letterhead stationery¹, the dateline is simply made up of the date of writing. Three points about date writing should be kept in mind. First, use the standard form, e.g., November 18, 1995; secondly², avoid using ordinal suffixes³ (-st, -nd, -rd, -th) which seem not only stiff but also out of fashion; thirdly, stay away from using abbreviations, hyphens, and diagonals, e.g. , 12-12-95, 2/2/95. 

On stationery without letterhead (as in the case in which individuals write a business letter), the writer usually places his own address, not his name, before the date:
15 Patrician⁴ Way New Jersey⁵ 13469
August 18, 1990 September 16, 1994 

　　在有抬头的信里，日期往往只是很简单地由写信日期构成。写日期要始终记住三点：1. 使用标准符号，比如November 18, 1995；2. 避免使用序数词的后缀，比如-st, -nd, -rd, -th，因为这些不光看上去拘谨也不符合潮流；3. 不要使用缩写、连字号和斜线，比如12-12-95, 2/2/95. 

在没有抬头的信里，比如个人写的商业书信，作者往往就在日期的前面写上自己的地址，而不是名字：
15 Patrician Way New Jersey 13469
August 18, 1990 September 16, 1994
