Always capitalize the names of months.
When a month is used with a specific date, abbreviate Jan., Feb., Aug., Sept., Oct., Nov. and Dec. Spell out March, April, May, June and July.
On the web, months are abbreviated to the first three letters (Jan, Feb, Mar, Apr, etc.) with no period in all instances.
Spell out all months when using them alone or followed only by a year. Do not use a comma between the month and the year. When a phrase refers to a month, day and year, set off the year with a comma.He graduated in May 2006 and began his graduate studies on Sept. 4, 2008.
