For what it's worth...
The day is a fixed period of time or a portion of time. You can also say throughout the ages. When you go through time it is like going through money (well besides one never seeming to have enough to spend on one's hobbies). Time in this case is a concept; you are not refering to particular points in the continuum.

As to the weather side of things, we too have had an abundance of rain this year, but such is life. It is either too hot, too cold, too wet, or too dry for someone, somewhere which is why when I was in training we were admonished to never say there was good weather in the forecast because everyone's definition of good is different. Personally, the only weather I dislike is hot and humid. As it is, I've been so snowed under (bad weather pun intended) that I the only weather I've had time to notice lately in on a chart.
