Multiple loops? – display days in reverse order, posts in asc

Hi there

I’d like to alter the display order of the posts on my index. I think I need to use multiple loops to do this…i don’t know what code to type into my template though. I’m hoping someone here can help.

What I’d like to do:
1. Index displays X posts (easy to do in control panel)
2. Index displays posts from today in ASCENDING order followed by posts from yesterday in ASCENDING order etc. etc.

example:
——————
#Header
//begin loop/s

Today: Post #1
Today: Post #2
Today: Post #3
Yesterday: Post #1
Yesterday: Post #2
Two Days Ago: Post #1
Two Days Ago: Post #2
———————–

I know how to use the WP_Query to show posts in ascending order.

I’m just wondering what to do to show the days containing these posts in descending order while still showing posts within the days in ascending order.

What do I add to my index.php?

Thanks
