Date format

It is often very useful to invert the date from the conventional sequence (day, month and year), and furthermore use underscores instead of full stops (dots) for file names.

Example

31.01.2012 → 2012_01_31 (preferred date format)

The main advantage of this format is that computer files can be sorted automatically by date when the files are displayed in a folder. Using the underscore ensures that suffix-based file associations (like *.txt) are maintained.
