Wikivoyage:Time and date formats
(Redirected from Tdf)
When giving times and dates, such as for opening and closing times of attractions, restaurants and bars, use the following formats.
- Consider using an en dash rather than a hyphen: 2–5PM, rather than 2-5PM; 09:00–13:00, rather than 09:00-13:00.
- Omit spaces before and after the dash or hyphen: 10:30AM–5PM, not 10:30AM – 5PM; 10AM–noon, not 10AM – noon; M–F, not M – F.
- Use one of these formats: 09:30–17:00 or 9:30AM–5PM. Do not use both 24- and 12-hour formats within one article. Choose between formats by following predominant local usage. Ask yourself which format visitors will see in timetables, on shop doors and in newspapers.
- It can be assumed that time is in the local time zone.
- For establishments that don't close, use: 24 hours daily
24-hour format 
- Always use two digits for the hours and two digits for the minutes (hh:mm). Include a leading zero for numbers below ten, eg, 09:00, not 9:00 or 09:0.
- Use a colon as the separator, eg, 17:30, not 17.30 or 17-30.
- Use 00:00 for midnight and 12:00 for noon.
12-hour format 
- Minutes are not shown for full hours: 5PM, not 5:00PM.
- Where minutes are shown, use a colon as the separator: 5:26PM, not 5.26PM or 5-26PM.
- Omit periods (full stops) in "AM" and "PM": 10:30AM–5PM, not 10:30A.M.–5P.M.
- Use noon and midnight, not 12AM and 12PM.
Days of the week 
- Abbreviate to the minimum number of letters, ie, M Tu W Th F Sa Su, in lists and where space is short.
- Spell out when it is part of a named day, eg, Good Friday, Fat Tuesday.
- If it looks odd or ambiguous in a particular context, spell it out.
- Separate two consecutive days with a space only, eg, Su M, not Su–M or Su, M.
- Separate days that are not in a range (eg, when a shop is open M, W and F, and closed on Tu and Th) with spaces only, eg, M W F 08:30–17:30.
- When combining days with time, put the days first, eg, M–F 10AM–2PM, not 10AM–2PM M–F.
- For all seven days, use: daily, not "every day" or "Su–Sa".
- Use the date format of dd mmm yyyy, eg, 10 Jan 2003.
- Abbreviate months to three letters, ie, Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec, in lists and where space is at a premium, such as in a table.
- Avoid using dates such as 10/1/03, 10-1-03 or 10/1/2003, as these can mean 10 Jan 2003 or 1 Oct 2003 to different people.
- Year or years: yr
- Week or weeks: wk
- Hour or hours: hr
- Minutes: min
