ISO 8601
This wiki and tango.info in general uses the international date format (w:ISO 8601). This eliminates ambiguities, makes searching the site and sorting events easier. A standard date format looks like: 2006-05-01
Examples for non standard local formats:
- 01/05/06 (does it mean 2001-05-06 or 2006-01-05 or 2006-05-01?)
- 1.5.06
- 1/5/2006
- 5/1/2006
- 1.5.2006
Time intervals are represented by start point and end point, seperated by "--":
Examples for standard representation of time intervals
- 2007-06-25--26 -> start: 2007-06-25 end 2007-06-26 (two days)
- 2007-06-25--29 -> start: 2007-06-25 end: 2007-06-29 (five days)
- 2007-06-25--07-01 -> start: 2007-06-25 end: 2007-07-01 (seven days)
- 2007-12-30--2008-01-02 -> start: 2007-12-30 end: 2008-01-02 (four days)
The ISO standard recomends "/" but allows "--" as a seperator. "--" can be used in filenames, so tango.info prefers this.
Time
Time is always written like 21:30. Time ranges should be represented like 21:30--23:45.
