It's Friday! ...or is it?

It's Friday! Hmmmm, unless the passage of time is an illusion, just positions along a coordinate system. In which case it's never really Friday. Or it always is, depending on how you look at it. But why does it feel like 'now' is Friday? Why isn't it Saturday or Thursday? Of course every other moment I've experienced feels like 'now' too, a week ago it felt like 'now' was last Friday, but NOW 'now' really is this Friday and oh dear I've gone cross-eyed again
