I don't know here you get the idea that those of us who enjoy a secular christmas only have two days of celebrations.
Christmas day and boxing day bank holidays.
Christmas lasts 12 days starting for most Christians at midnight on Dec 24th, this is the period or time I am referring to.
You seem to think that some of the things you do in Advent are 'cellebrating Christmas' they are not.
Who are you to judge what determines christmas celebrations! Jesus may be part of your idea of christmas- but it isn't mine.
Well considering I don't celebrate Christmas whether Jesus is part of yours or not is neither hear nor there. So how did you celebrate on the 28th of December? What did yo do on Jan 4th?
I asked a question about the celebration of Christmas by Christians in exactly the same way as I might ask a Muslim about how they celebrate Eid or a Hindu about Divali and quite frankly as you are not a Christian you telling me what you do at a time of year that is not a Christmas for Christians is irrelevant.
You could decide to put a tree up on July 12th, it would not make Christmas move to July for Christians (btw some Christians don't have Christmas day until Jan 6th, I bet you are not celebrating that are you).
