Question

Q1. Does a recipient's address mean a receiver's address?

Q2. Are the following all correct? They are for the date under the sender's address?

1. 29/4/92
2. 29th March 1992
3. 29 March 1992

4. 4/29/92
5. March 29th, 1992
6. March 29, 1992
(#1,2, and 3 seem to be used in British English. #4,5 and 6 seem to be used in American English. In AE, do we have to put a commar before the year?)

Answer 1

Q1 -- yes

Q2 -- #3 and #6 are the best; #1 and #4 are too informal to be used in a formal letter, and #2 and #5 don't need the "th."

Answer 2

Thank you.

How do you read " March 29"
1. March twenty-nine
2. March twenty-ninth

Answer 3

#1 is how you read "March 29"

Usually, we use the -th when we aren't using the year. However, even when we write March 29, 2015, the -th can be pronounced, even if it's not written.
