That is a nice way of seeing it.

So you (as a christian) wouldn't have a problem with the statutary holidays (ie the state supported holidays) being around the solstice...

And where different people of different faiths could of course celebrate whatever they wanted whenever the wanted (as people who aren't christian do anyrate).

I guess the difference would be... That one religion wasn't prioritised over another and instead the state supported holiday would be based on the original tradition (of celebrating the shortest day)

Also... Us peoples in the southern hemisphere could celebrate the longest day...

And we could do things at the other end too (we often do over here and call it 'mid winter christmas' though isn't that another solstice too???)
