Notes on Writing Out Numbers and Years:

  • 1: In American English, unlike British English, when writing out years of three or more digits, the word 'and' is not used after 'hundred' or 'thousand'; i.e. 963 is written out as 'nine sixty-three' (American English) and not as 'nine hundred and sixty-three' (British English); 2025 is 'two thousand twenty-five' (American English) and not 'two thousand and twenty-five' (British English).
  • 2. Up to 1999 the years are spoken as hundreds, but for shortening, the words 'hundred and' are omitted: i. e. 1999 = 'nineteen (hundred and) ninety-nine' = 'nineteen ninety-nine'.
  • 3. After the year 2000 the years are spoken as normal numbers, but for shortening, in colloquial language, the years are pronounced in groups of two: i. e. 2000 = 'two thousand'; 2001 = 'two thousand (and) one', but also 'twenty oh one'.
  • 4. Do not use commas when writing in digits years above 999; i.e. it is 1234; 1973, 2021, and not 1,234; 1,973, 2,021.
  • 5: It's correct to hyphenate all compound numbers from 'twenty-one' (21) through 'ninety-nine' (99). The hyphen is the minus sign, as in 'thirty-four' (34).
