Should we change the year? |

Put the mulled wine down and sleep it off.

Technically it isn't fine, as we date things from the birth of a historical figure that may or may not have existed, and certainly may not have been the son of God.
We should be trying to date things from both the beginning of the Universe and from when Humanity first evolved. |

Supposed birth ? Do you think that he just appeared on earth as an adult ?
May or may exisited. His birth was the most significant thing in history. Only that it is a few years out ![]() and what is the start of the common era based on ? Your days would be too long unless you altered the time of the second. All watches and clocks would be automatically useless. It would be a bonanza for the clock and watch making industries, creating many jobs. |

Yes the second would be a little bit shorter, approx 0.8 of a current second.

There's no need to change to another system when we start colonising other planets and moons.
They can just adapt to Earth time and bloody well like it! Another planet, or moon isn't going to have that. Sure, it'll likely have seasons, orbits and the like, but they'll all be well out of sync with Earth-time, and thus (somehow) a new time/date system will need to be implemented to unify everything. The mathematics of this are beyond me, but I think it would be a struggle for everywhere else to work on Earth time. |

I don't think it'll be quite that simple. We have Earth time because of our very unique circumstances, 356 days per rotation, 12 seasons, 24 hours in a day (etc).

Pretty much everything else is man-made and can be changed. |

I remember when I was at school getting into trouble for using AD and BC on a essay. I was told CE (common era) and BCE ( before common era) was more politically correct.

Our rotation is apparently slowing down though I can't remember offhand to what extent so the degree of orbital slowing might be even higher. Something about the moon and the big watery thing sloshing around the wrong way. |

Noting also that there are 360 degrees in a circle, this tells us that either the earth's orbital speed has slowed down such that it takes five days longer than the original design of one degree per day, or there was a miscalculation, or even that the gravity has worn off a bit and we don't need to go so fast.
Unless ypu were being ironic/humorous edit to add: which on a second reading I think you were being. |

But in between 360 degrees in a circle and 365 days in a year, we can throw in stuff about observable stellar drift, stonehenge, pyramids, pole stars that aren't pole stars, moving magnetic poles etc etc giving us more than enough room for some theory about aliens probed my goldfish and made the earth's orbit so it's not a circle any more and 365 instead of 360 to go all the way round, and if there isn't a theory about that somewhere out there, I'll be needing some ketchup for this hat

12 seasons? 12 months you mean.

If we one day colonise another world, the people born on that world aren't going to know Earth time; they'll know only the time that they're born into (if that makes sense?) Whilst a day on another planet will still be a day, it may be two hours longer, or two hours shorter than a day on Earth. Some genius is going to have to calculate how, as that's beyond me. |

Would it still be 24 Earth hours or as long as 28 Earth days? |

If people are really so offended they should use an entirely new system (French revolutionary calendar perhaps?) rather than stick a meaningless term on a Christian based one. |

Yeah, months, sorry.
Whilst true, a day is a day, the length of a day is quite likely to vary from the perspective of another planet. If we one day colonise another world, the people born on that world aren't going to know Earth time; they'll know only the time that they're born into (if that makes sense?) Whilst a day on another planet will still be a day, it may be two hours longer, or two hours shorter than a day on Earth. Some genius is going to have to calculate how, as that's beyond me. |

That's interesting, how long ago was that? I'd never even heard the terms CE and BCE before reading this thread.
