I think it depends. Does day one have an aftermath? If it does, writing about said aftermath on day two would be interesting - though maybe not in great detail; perhaps gloss is the word, but I tend to associate that with handwave, which isn't quite what I mean. More like a short transitionary vignette - and then getting smacked between the eyes with day three would be more effective. But it really depends on what the events are, more than anything.

So, uh. In short: definitive answer needs more context!
