dates (also see numbers section)
In running text avoid inserting "nd" or "st" (use April 23, not April 23rd)

When days of the week are used alone always spell out. Days of the week may be abbreviated when used in conjunction with month, day, and year

Always spell out months when using alone. Okay to abbreviate months when followed by a date (Jan. 6, 2004). Never abbreviate March, April, May, June, or July.

Consecutive dates can be written in two ways: by inserting an en dash

Use "through" when dates extend from one month to the next.
