Blog View- order of days in week showing?

OK I didn't think I did anything to change this, but I just clicked on my training log and the view now shows my dates starting from today and going forward in time as you scroll down the page.

It used to start with today's date and as you scrolled down showed previous days.

Not sure if that made sense.... anyway, it appears that way when I click on other people's logs too so I don't know if there's some setting or something that I clicked accidentally to change my view? Any thoughts??
