What are -list- the Scientology religion holidays? and try to arrange them according to its priorities?

The dates Scientology celebrates or commemorates annually as a religion are:

March 13th Birthday of L.Ron Hubbard (1911)

May 9th Date the book " Dianetics the Modern Science of Mental Health" was first published (1950)

June 6 Maiden Voyage of the Freewinds. (release of the first advanced spiritual levels) (1985)

September (second Sunday) Auditors Day. (celebration and acknowledgement of all Scientology Auditors)

October 7 Founding of the International Association of Scientologists (1984)

These are all important dates or milestones for our religion, but the most important one is March 13th the birthday of L.Ron Hubbard.

We don't celebrate New Year's Eve as a religion , we do have an event on that date to celebrate our major achievements and advances internationally as a church for the year just ending and make plans as a group for the New Year .

I couldn't find anything about priorities, so I've just listed them in chronological sequence:

March 13 – the birthday of L. Ron Hubbard

May 9 – the first publication of ‘Dianetics’

June 6 – the maiden voyage of the ‘Freewinds’

September (second Sunday) – in honour of all auditors

October 7 – the founding of the International Association of Scientologists

December 31 – New Year’s Eve

What Lynne says is entirely accurate. She has the correct reasons for the holidays. New Year's Eve is not a Scientology holiday.

L. ron Hubbard's birthday is by far the biggest holiday. Every year Scientology hosts a big event where they salute a giant Stalin-like portrait of Hubbard. It's really creepy. They worship th dead one nutcase.
