months and years

Capitalize the months in all uses. When a month is used with a specific date, abbreviate only Jan., Feb., Aug., Sept., Oct., Nov., and Dec. (Jan. 9, 2008). Also abbreviate these months in tables; however, omit the period. Spell out months when used alone or just with the year, and omit commas when the month and year appear together (October 2001).

Use a lowercase s (no apostrophe) to show the plural of a decade expressed with numerals (e.g., the 1990s).
