You have a sample size of less than 60 days -- or rather, 11 days, which I believe is the duration of your stay. In addition, a changeover in power has occurred, and so your total sample size of holidays under this warden is 1.
In the time you have been here we have celebrated 3 holidays: an Earth Japanese holiday, an Earth secular holiday, and an Earth Christian holiday. This is a wide range of holiday activity, albeit mostly Earth-originating; the vast majority of our residents are from some version and time of Earth, at my last determination. My impression from the greeting was that Acumen surveyed whether or not there would be interest in a religious ceremony before engaging one of our resident clergy to conduct it. All previous holidays had been celebrated in a secular fashion.
......Yes, I am Sentience. [after a noticeable pause. we are clearly much more comfortable rattling off facts than talking about ourselves!] I was tried and incarcerated for my crimes.
