When a new list item is added, I'd like a date field (Date From) to be defaulted to Monday of this week, as well as another date field (Date To) to Sunday of next week (creating a 1 week span Mon-Sun). So no matter what day of the week it currently is, these date fields would default to this week's date range.
Can I accomplish this using just the column's default value? If so, how?
Please note I barely know anything about SharePoint and am learning as I go, so I'd prefer a method which doesn't require programming (even though I'm willing to do so if I have to).
