If you want to mention a certain time you say :
1) dated 01/07/2007
2) dated on 01/07/2007
This is the context:
" With reference to letter No. 123 dated (on) 01/07/2007, we would like to inform you that ... "
"With reference to letter [ref] dated [date]" would be the normal phrasing here.
Since shortly after 'TIME' began in 1923, each issue has been dated on Monday. Beginning with this issue, in keeping with the new earlier press schedule established in recent months, 'TIME' will be dated as of Friday.
The letter dated 01/07/2007 ...
The date is important
The letter dated on 01/07/2007 ...
The one below is different without on:
Ex: Since shortly after 'TIME' began in 1923, each issue has been dated Monday.
The word Monday is part of the date.
I agree that "dated" and "dated on" are different, and we should only say 'The magazine was dated Monday, June 18th, 2007.'
"dated on" should mean the day that the date was printed on the magazine or product. For example, some product is produced every day of the week, but all the products are dated on Tuesdays. This means that the expiry date, for example, is stamped on on Tuesdays.
Back to the magazine covers, since the June 18th edition appears for sale on June 11th, it obviously was not dated on June 18th but is dated June 18th.
This seems to be an interesting point. Casiopea, I have not quite understood your explanation. Is it all about the importance of the date?
Your opinion seems to contradict (or at least it doesn't fully agree with) 2006's.
Could you two try to re-explain it?
Isn't a synthesis of your opinions possible? Or the difference between your opinions is just due to you living in different places?
I'm afraid I really can't grasp the difference between dated and dated on. Is it really just a matter of importance? Is it just a nuance or does it completely change the meaning of the sentence?
