I fully ejected "Christmas" and "Easter" from my life. Of course I retained Mosaic Firstfruits and also celebrated it as Resurrection Day (which is an internal question among 7th-day resters). Funny thing, 25 years later, I discovered there's enough evidence that the Christian tradition of Julian December 25 might well point to a confused echo that Jesus's annunciation, conception, "epiphany", genesis, and "nativity" might have occurred on 25 Dec of 5 BC, corresponding to his birth on the first of Tabernacles (6 Oct) in 4 BC. One intriguing line is that Haggai 2 prophesies this date as 24 Kislev and Simeon makes about ten references to Haggai 2 suggesting he could've recognized and approved the date.

Therefore one thing we need to do in getting along with those rampant 1st-day resters is to be open to a couple hints in the text that there may be good symbologic significance to some things they day even as they are overcome by evil symbologic significance that has infiltrated their practice unconsciously. There is a way by which everything is pure to the pure. Celebrating Mosaic Firstfruits and a 25 Dec conception nativity can be done without sin. (Technical note: for Gregorian-Julian alignment of 2 days the celebration should begin the evening of 23 Dec, making 25 Dec more of a diaspora date; but getting off work the evening of 23 Dec is what people do nowadays anyway.)
