Write dates back to front
Rule 5: If using a date in the file name always state the date 'back to front', and use four digit years, two digit months and two digit days: YYYYMMDD or YYYYMM or YYYY or YYYY-YYYY.
Dates should always be presented 'back to front', that is with the year first (always given as a four digit number), followed by the month (always given as a two digit number), and the day (always given as a two digit number). Giving the dates back to front means that the chronological order of the records is maintained when the file names are listed in the file directory. This helps when trying to retrieve the latest dated record.
Example
- Correct file name
- 20040324Agenda.rtf
- 20040324Minutes.rtf
- 20040324PaperA.rtf
- 20050201Agenda.rtf
- 20050201Minutes.rtf
- (Ordered alphanumerically as the files would be in the directory list)
- Incorrect file name
- 1Feb2005Agenda.rtf
- 1Feb2005Minutes.rtf
- 24March2004Agenda.rtf
- 24March2004Minutes.rtf
- 24March2004PaperA.rtf
- (Ordered alphanumerically as the files would be in the directory list)
- Explanation:
