Template:Help:Dates and numbers

• Write number 1 or No. 1, but not #1. Comic books are an exception.
• Write 12,000 for twelve thousand, not 12.000.
• Both 10 June 1921 and June 10, 1921, are correct, but be consistent within an article. A comma is not used if only the month is given, such as June 1921.
• 400 AD and 400 BC are correct; but so are 400 CE and 400 BCE. As always, use one style consistently in an article.
• Use one, two, three, ..., eight, nine in normal article text, not 1, 2, 3, 4, 5, 6, 7, 8, 9 (although there are many exceptional circumstances; and some other numbers may be written as words also).
