There are now special site background colors based on the time of month.

Winter Months (12, 1, 2) get a white background for snow,

Spring Months (3, 4, 5) get the Green background from before,

Summer Months (6, 7, 8) get a Yellow background,

Fall Months (9, 10, 11) get a Orange background.

I also added a few special days with their own colors.

Feb 14 and Mar 14 get a pink background.

Feb 15 gets a purple background (site anniversary).

I will probably add more colors for other days throughout the year but not reveal them, a secret.
