Wikitravel:Time and date formats
When giving times and dates, such as for opening and closing times of attractions, restaurants and bars, use the following formats:-
Use the 24 hour clock eg: 10:30-17:00
In 24-hour format, always show minutes using a colon as the separator; eg: 17:00, not 17.00 nor 17-00 and not just 17 and never 17:0.
For articles about topics where the AM/PM system (or 12-hour format) is prevalent, the following format can be used as an alternative: 10:30AM-5PM.
Choose to deviate from our 24 hour standard format only to follow predominant local usage. Ask yourself: which format will visitors see in newspapers, on shop doors, and on train schedules?
Days of the week
Abbreviate to the minimum number of letters, ie: M Tu W Th F Sa Su.
Use the date format of 10 Jan 2003.
Abbreviate months to three letters, ie: 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.
