|Month||Cat Lover's month|
|4th||National Kitten Day (again)|

Evidently, there are other holidays that are taking up the time of people who would be making up new kittydays.
Hannukah / Chanukah runs from sunset on the 12th to sunset on the 20th this year.
The earliest sunset for most of the Northern Hemisphere is sometime in the first week, with the shortest day on the Solstice of the 21st, followed by the latest sunrise sometime in early January. Check your local listings.
