When giving times and dates, such as for opening and closing times of attractions, restaurants and bars, use the following format.
Use one of the following formats: 10:30AM-5PM or 10:30-17:00. It can be assumed that time is in the local timezone.
Use "noon" and "midnight", not 12AM or 12PM or 00:00.
- In 12-hour format, minutes not shown when not required, e.g., 5PM, not 5:00PM.
- In 24-hour format, always show minutes, e.g., 17:00, not just 17.
- Where minutes are shown, use a colon as the separator, e.g., 17:30, not 17.30 or 17-30.
- Spaces and periods (fullstops) should be left out, e.g., 10:30AM-5PM, not 10:30 A.M. – 5 P.M.
- Spaces should be left out for noon and midnight too, e.g., 10AM-noon.
- Choose between 12- and 24-hour formats by following predominant local usage. Ask yourself: which format will visitors see in newspapers, on shop doors, and on train schedules?
- If using 24-hour format, make sure that's clear; if there are no times after noon, consider using the 12-hour format (with the "AM") to avoid confusing readers expecting a 12-hour format.
Days of the week
Abbreviate to the minimum number of letters, i.e., M Tu W Th F Sa Su.
- Spell out when it is part of a named day, e.g., Good Friday, Fat Tuesday.
- If it looks odd or ambiguous in a particular context, spell it out.
- Spaces should be left out, e.g., M-F not M - F or M thru F.
- Leave the dash out for a pair of days, e.g., Sa Su not Sa-Su.
- When combining days with time, put the days first, e.g., M-F 10AM-2PM rather than 10AM-2PM M-F.
- For all seven days, use "daily". Do not use "every day" or "Su-Sa".
Use the date format of 10 Jan 2003.
Abbreviate months to three letters, i.e., Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec.
Avoid using dates such as 10/1/03, 10-1-03 or 10/1/2003 as this can mean 10 Jan 2003 or 1 Oct 2003 to different people.
