Rails has beginning_of_week, however that is one specific definition of week. If you have a look inside it's easy to adapt that.
You just need to look at Time.now.wday, which varies from 0 (on a sunday) to 6 (on a saturday). So if your weeks start on thursday then you're looking for the previous/next date with a wday of 4. You can do this naively by just adding a day at a time until some_date.wday has the right value or you can work out the increments yourself. it's just arithmetic modulo 7. if d is the number of days until the next thursday, and n is Time.now.wday then it must be that n+d = 4 [7] so d = 4-n [7] ie d = 4-n +k*7 for an appropriate value of k. So days until thursdays are given by d=4-n + k*7. If you want the next thursday then that imposes 7>=d >0 so if 0 <= n <4 (ie today is sunday through wednesday) then k = 0, so d = 4 - Time.now.wday if n>= 4 (thursday through saturday) then k = 1 so d = 11 - Time.now.wday and similarly for finding the previous thursday (this is probably an overcomplicated way of reasoning about this - showing my background here) Fred > I have spent hours pouring over: > > The Ruby on Rails Bible > and Ruby on Rails Unleashed > > books as well as google but still hitting road blocks. > > Can someone help me out and describe to me how to: > > 1) Figure out the dates > 2) Display them on the web page.
