Will will refer to this filter later as Filter 1. As you can see, the filter is starting to take shape. Now lets say we are going to always be looking at a date range of the most recent completed 6 months.

It will look like this: Now we have a filter that is greater than or equal to the first day of the month of any given date default of today 6 months ago. We will refer to the following filter as Filter 2: For more on how to create a prompt with a range of values by altering a current column, like we want to do to allow users to select a value for n, click here.

The only date order that is consistent with these well-established conventions is year-month-day. A plain text list of dates with this format can be easily sorted by file managersword processorsspreadsheets and other software tools with built-in sorting functions.
Naming folders with YYYY-MM-DD at the beginning allows them to be listed in date order when sorting by name - especially useful for organising document libraries.
