This reminds me of my recent meaning of Christmas thread... how Christians pinched the season from the pagans and rebranded it as being about Christ (even though he wasn't even born in the winter season); and now in more recent times its being steadily secularised in order to remain a relevant feature on our calendars. To stay alive. Basically, Christmas evolves - and changes its fundamental meaning - throughout the ages to keep up with a changing society. To remain relevant to as many people as possible in today's society - where Christianity is no longer dominant in most people's lives like it once was (whether we wanted it to be or no). It made the transition from various pagan belief systems into a monotheistic-faith inspired worldview... now it is (successfully) making yet another transition to survive an ever-more secular epoch.
Yet, it should be pointed out that some Christian faiths denied Christmas' legitimacy as a Christian event because of its true pagan origins and the simple truth that December was not the month of Christ's birth - ie. Quakers, Presbyterians, etc. I've seen Fox News recently try and portray athiests as having a "war on Christ-mass" and "keep the Christ in Christ-Mass" when in reality many Christian denominations (very plausibly and coherently) deny this connection too. In my (officially Christian) country, Christmas was not recognised as a holidy until well into the 1950's.

It was an ordinary working day just like any other. Our national church seen it as a pagan invention: not genuinely Christian at all. We only marked New Year and to this day New Year, not Christmas, is our main festivity.

Nowadays, it embodies different things to different people. Thats a right everyone has. I think its a great thing.

It may even indeed warrant a new name - it was once called Yuletide (among various other pre-Christian names), then 'Christmas' to symbolise its newly created meaning; now it may indeed yet again warrant being renamed in the future. As they say... adapt or die.
I'll stick to a nice innocent secular 'Season's Greetings'

and Happy New Year message to everyone, lol!

Best,
