Dates, Months, Years, Days of the Week
For dates and years, use figures. Do not use st, nd, rd, or th with dates, and use Arabic figures. Always capitalize months. Spell out the month unless it is used with a date. When used with a date, abbreviate only the following months: Jan., Feb., Aug., Sept., Oct., Nov. and Dec.
Commas are not necessary if only a year and month are given, but commas should be used to set off a year if the date, month and year are given. Use the letter s but not an apostrophe after the figures when expressing decades or centuries. Do, however, use an apostrophe before figures expressing a decade if numerals are left out. Examples: Classes begin Aug. 25. Purdue University was founded May 6, 1869. The semester begins in January. The 1800s. The ’90s.
If you refer to an event that occurred the day prior to when the article will appear, do not use the word yesterday. Instead, use the day of the week. Capitalize days of the week, but do not abbreviate. If an event occurs more than seven days before or after the current date, use the month and a figure.
