What's the correct way to format a date range, time range, and days of week in a single line? [closed]

english.stackexchange.com › questions › 107197 › whats-the-correct-way-to-format-a-date-range-time-range-and-days-of-week-in-a

If you are required to keep that level of detail, you could write

June 3–7 (Monday–Friday), 2013, 8:30 a.m.–5:30 p.m.
or
Monday–Friday, June 3–7, 2013, 8:30am–5:30pm daily

The Associated Press Stylebook as synopsized at a www.wwu.edu/journalism webpage recommends the forms a.m. and p.m. rather than am and pm. In my opinion, 8:30–5:30 is an adequately unambiguous designation for 8:30 a.m.–5:30 p.m. and I'd write things like the following, in spite of having no authorities to directly support these forms.

M–F 8:30–5:30 daily, 3–7 June 2013
or
3–7 June 2013 (M–F 8:30–5:30)
or
3–7 June 2013 (M–F 8:30–5:30 daily)

r/grammar on Reddit: Need your thoughts on A.M and P.M and time ranges

March 12, 2018 -

I'm trying to figure out what the best way to write P.M and A.M when indicating time ranges. For instance, if you're writing a schedule for something like a yoga class, is it really necessary to put P.M and A.M on both sides of the time range? Take this example:

Monday: 9:30-10:45 AM Tuesday: 9:30-10:45 AM Wednesday: 3:15-4:15 PM Thursday: 9:30-10:45 AM

I think the context being a schedule for a Yoga class implies that the sessions aren't going to be 10+ hours long, i.e. it kind of just makes sense that 3:15-4:15PM is an hour long, and that '3:15' indicates 3:15 PM and not 3:15 AM. It seems redundant to include a P.M after 3:15 for that reason. What are your thoughts?

Not so much a grammar question rather than a style question. So, IMO, the answer is do what you prefer, really. However, AP style dictates that you only need a.m. or p.m. when dealing with times that both fall in the a.m. or the p.m. If you had a class that started in the morning and ended in the afternoon, the suggestion is to use both a.m. and p.m. (11 a.m. - 1:30 p.m.) AP further states that you use "noon" and "midnight" instead of 12 p.m. and 12 a.m.

Typically, write The Norman Conquest took place in 1066 not 1066 CE or AD 1066. But Plotinus lived at the end of the 3rd century AD (not simply at the end of the 3rd century) may avoid confusion unless the era is clear from context. One- and two-digit years may look more natural with an era marker (born in 2 AD or born January 15, 22 CE, not born in 2 nor January 15, 22). Ranges beginning in BC / BCE should specify the ending era: write 450 to 200 BCE or 450 BC to 200 BC or 450 BCE to 200 CE, but not 450 BCE to 200.
