On Using Date Formats in Filename

When using a date as part of a filename or directory name, you should follow the format yyyyMMdd (at least in that order). I cringe every time I find some other formats. Having the date in this format allows it to be sortable.

20171014 is easier to work with than 10_14_17.

While we’re on the topic, you should be using 24 hour time formats too.
