Many of the greatest authors ever are, through the sheer unfairness of the universe, dead. Pterry is the most recent, of course. Now, when renowned and beloved religious figures die, they might get made into saints... so why not do the same with the authors we mourn?
I'm leaving theology out of it (though the idea of dead authors interceding with a Great Author to demand a better plot has a certain appeal...); this is a liturgical calendar without the liturgy. It's just for fun, in other words (though if it produces enough results, I might add a page to the Temple of All Faiths).
Here's the ones I've come up with:
Saint Pterry of Ankh
Patron of: Humour, primates, turtles.
Symbols: the Ankh, the Lilac.

Feast Day: 25th May (the Glorious Twenty-Fifth)
On the Glorious Twenty-Fifth, it is traditional to bake a loaf of dwarf bread and refrain from eating it.
Saint Douglas of the Galaxy
Patron of: Humour, travellers.
Symbol: the Towel.
Feast Day: 25th May (Towel Day)
The traditional feuds between those who wish to venerate Saint Douglas and those who prefer Saint Pterry have been overcome in recent years by the creation of lilac towels.
Professor Saint Tolkien
Patron of: Fantasy, separated lovers, singers.
Symbols: the Star, the Ring, the Jewel.
Feast Day: 25th March (the end of the Third Age)
Celebrating Professor Saint Tolkien, followers will eat a Hobbitish meal in the evening and then spend the night under the stars.
Saint Anne of Dragonhold
Patron of: Riders, musicians, pilots, astronauts.
Symbol: the Dragon.
Feast Day: 1st January (TurnOver)
Saint Anne is best remembered with a mug of hot klah.
What can you add? The only requirement is that they have to be... y'know... dead. Living saints tend to be a bit awkward.
