Written Dates and Times
Dates should be formatted as day month, year i.e. 9 March, 2013.
Capitalize the names of months in all uses.
Where necessary when a month is used with a specific date,
you may abbreviate months as follows: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec i.e. 9 Nov, 2013.
Spell out in full when using alone, or with a year alone i.e. November 2013.
When a phrase lists only a month and a year, do not separate the year with commas.
When a phrase refers to a day, month and year set off the year with a comma.
Times should be formatted as zulu time and any local time differences should follow in brackets, i.e.
19:00Z (23:00 IST)
Machine Specific Dates
To maintain a standard for dates used within the computer systems of IVAO a format taken from the ICAO "Machine Readable Official Travel Documents" text has been adopted.
This date format should be used whenever a date is input, displayed or refereded to in connection to any computer systems. This format may also be freely used in documnets such as event dates, meeting dates or publication dates.
The representation of these dates follows the format DD MMM YYYY.
Days shall be shown by a two-letter number, i.e. the dates from one to nine shall be preceeded by a zero. This number shall be followed by a blank space.
Months shall be abbreviated using three character positions as follows: JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC.
The year shall be shown as four digists preceeded by a blank space.
Examples: 4 June, 1966 would be represented as 04 JUN 1966 and 8 September, 2002 would become 08 SEP 2002.
Spell out whole numbers up to and including nine (e.g., zero, one, 10, 96, 104).
Spell out casual expressions: "A picture is worth a thousand words, but a really good one is worth a
Spell out numbers that begin a sentence unless it begins with a year (e.g., "Twelve drummers,"
"The 10 lords a-leaping," "2011s quota for off-season holiday references has been filled.").
For percentages, use numerals with "percent" not "%".
Spell out ordinal numbers up to and including "ninth" when indicating sequence in time or location
(e.g., first kiss, 11th hour) but not when indicating sequence in naming conventions (usually geographic, military,
or political, e.g., 9th U.S. Circuit Court of Appeals).
