I have a view which includes a date field, and I'd like to provide a filter for users to show only items from a certain day of the week. From what I can see, though, the date filter only allows you to select the date by which to filter. Is it possible to create a filter which will allow users to show, say, all nodes which have a date that falls on a Wednesday?
I think you have to use the Views Day of Week module to filter the result by day of week. Here is a quote from it's project page:
... Views Day of Week provides a simple filter plugin for Views 3 to enable filtering content that should be visible based on the current day of the week.
Example: With this module you can select that some content should be visible only on Mondays, some on Tuesdays and Thursdays and some only on Fridays.
