When giving times and dates, such as for opening and closing times of attractions, restaurants and bars, use the following formatting guidelines.

Times

Use either the 24-hour format (09:30–17:00) or the 12-hour format (9:30AM–5PM). Do not use both within one article – choose one by following predominant local usage. Ask yourself: "Which format will visitors see in timetables, on shop doors and in newspapers?"

It can be assumed that times are in the local time zone.

Regardless of format

24 hours daily	For establishments that don't close use "24 hours daily".

12-hour format

9AM	Minutes are not shown for full hours. Don't use spaces. Omit periods (full stops) in "AM" and "PM".
9:15AM	Where minutes are shown, use a colon as the separator.
midnight noon	Use "midnight" for 12PM and "noon" for 12AM.
9:15AM–5PM 8–11AM	Separate a range with en dash rather than a hyphen. Don't use spaces. Use "AM" and "PM" only once for a range when both parts are AM or PM.

24-hour format

09:00 09:15	Always use two digits, both for the hour and the minutes. (Minutes, i.e. zeroes, are shown for full hours.) Include the leading zero Use a colon as the separator.
00:00 12:00	Use 00:00 for midnight and 12:00 for noon.
09:15–17:00	Separate a range with en dash rather than a hyphen. Don't use spaces.

Days

M Tu W Th F Sa Su	Abbreviate days to the minimum number of letters. (Do so only in lists and where space is short.)
Good Friday	Spell the day out when it is part of a named day.
M–F	Separate a range with en dash rather than a hyphen. Don't use spaces.
M Tu	Separate two consecutive days with a space only.
M W F	Separate days that are not in a range with spaces only.
M–F 09:15–17:00	When combining days with time, put the days first.
09:15–17:00 daily	For all seven days use only "daily".
3–11PM (closed Tu)	For establishments open six days a week, state the day they are closed.

Dates

1 Jan 2001	Use the date format of day–month–year. Day: Use two digits, without a leading zero. Month: Abbreviate to first three letters where needed (lists, listings, etc.). Year: Use four digits.

Durations

2 yr	Years
2 wk	Weeks
2 hr	Hours
2 min	Minutes
5 hr 15 min 5¼ hr	Hours and minutes (stick to one style for the whole article).

Decades and centuries

the 1920s	Decades should be shown in digits Do not use "the twenties" or "the 1920's".
the 19th century	Centuries should be shown in digits. (Do not use "the XIX century", "the nineteenth century", or the "19th Century".) Also consider whether to use, for example, "the 1800s" instead of "the 19th century".
