Always spell out names of months when it stands alone, with specific years and when space allows. If necessary, only use abbreviations when used with a specific date.
Always use numerals as dates. Do not add suffixes (th, st, etc.) to numerals unless used for street names.
When using a specific date in running text, use a comma after the year. However, do not use a comma to separate the month and year when there is not a specific date.
Use four digits when referencing a specific year (2008).
When referencing a range of years, it is acceptable to use a two-digit year (2008-09).
If using numerals for the month, day and year (only recommended for informal documents) the format is as follows: MM/DD/YYYY, MM-DD-YYYY or MM.DD.YYYY.
If the date referenced occurs in the current year, the year is not necessary.
Use figures for time, except for noon and midnight.
Use a colon to separate hours and minutes. Do not add a colon and zeros for on-the-hour times
Specify the time of day by using a.m. or p.m. (lower-case letters with periods and no spaces between).
Avoid redundancies such as 10 a.m. in the morning.
