Last week we studied Wikipedia's exception-filled rules on dealing with numbers, and this week we focus on how to write about dates and times.
All OK: 13 October 2016; October 13, 2016; 13 October; October 13; or October 2016
Not OK: Pretty much everything else. Only abbreviate months when needed for brevity, and do not use periods. Do not abbreviate years (use 2016, not '16)
When telling time, the numbers should be styled like 10:10 a.m. Use midnight and noon for 12 a.m. and 12 p.m. Using a 24-hour clock does not require a.m. or p.m.
Bonus: Stay away from words like "currently", "recently", and "so far"; they are ambiguous and quickly become outdated.
