Indeed, I talked to padren long ago about this. As for other festivals:

The Mourning Day - Day after the Ackbar attack, to mourn Kamuii and Henry Nightrose.

The Hyr'Zern Festival - A glorious holiday in which the Cardinal of Dustari and the High Prophet of Zormite may come together and divine the will of the gods to fortell a joyous or desperate year.

This is harder than it looks...
