The letter "C" before a birth date stands for "Circa" which means "about." It means that the date is not certain, but is approximate.
No. The conception date is about 9 months or 40 weeks before the date of birth.
His birth date is unknown.
Always use the date your are writing the letter as the date of the letter. UNLESS, you are writing the letter on a date before when you will send the letter. In this case, use the date that the letter will actually be sent.
That depends what your date of birth is, you can simply represent the month with a number so that, for example a date of birth like 12th October 1539 could be written as 12-10-1539 and these numbers could be represented by the Roman numerals XII.X.MDXXXIX
I don't know his death date, but his birth date is January1st one year before Christ.
A letter?? Not a number?? It goes after the date: 753BC. (meaning Before Christ)
The dates are the person's birth and death dates. The dash signifies the time in between. It's like saying "this person lived from <birth date> until <death date>". Actually the dash would not mean "until" since the word until would imply that the death occurred prior to that date happening. The dash would mean he lived "to" the point in time, the word "meaning" not before and not after that date, but not specifying a time.
can you break up a will before reaching the date of birth stated on it?
61, assuming a date of birth on, or before, this date; otherwise, you would be 60.
He was born in 1451 before the 31st of October
The date of a letter should always be the date that the letter is sent. If there is a time frame that an authorization will be effective, that time frame should be stated in the content of the letter or a reference line before the start of the letter.
Personaly, i'd say date of birth. Both ways are correct, though
