@skeptic2girl; I know what Narconon Day is!
A fake Co$ holiday invented by LRH.
The "Countdown to" website is just a commercial advertising vehicle. Countdown to whatever religious or secular holiday in whatever year you can imagine; from Christmas to Pentecost for Christians, Independence day of 17 countries for secular humanists, Pesach for the Jews, Eid-el-Fitr for Muslims, Samhain for Neo-Pagans and thus also LRH's birthday and Narconon day for the Scientologists among the public.
We would not want to discriminate against members of an alternative religion, would we?
Oh yeah, we would.
