New Year Science you NEED to know and probably didn't !

Posted this in another thread but just thought I would start a new thread on it

For the science crowd, last leap year was 2020, a year on earth is actually 365 1/4 days hence adding 6 hrs each year and taking that full 24 hrs once every 4 years (or the leap year)

So in 2021 the new year technically started at 6 am on Jan 1 (adding 6 hrs to the midnight hour), this year new year is technically noon on the first (6 am plus 6 hrs) and so on

Now you too can get kicked out of parties for being a nerd LOL! Happy New Year (tomorrow at noon I mean)

You are right, I didn't know and more importantly I don't care.

Not much of a nerd you forgot seconds plus you forgot that the earth is slowing down over time so this changes by fraction time every year.
Correct your work and get back to us!
Bonus points if you include the other factors that I did not mention hint milder minimum.

You're a nerd credentials or at risk!

Actually, that is not quite true:

The Earth's orbit around the Sun actually takes 365.2422 days (sidereal year). The problem with the 365 day calendar is that it does not quite cover a full Earth orbit. Using a Leap Year (adding a day every 4 years) is overcompensating a bit, since it assumes a 365.25 day orbit, which also isn't quite true. This is why the Leap Year is skipped every whole century, except for one that is divisible by 400. So, the year 1900 was not a Leap Year, but the year 2000 was.

What you had described was true in the Julian calendar. However, we now use the Gregorian calendar, which uses that small correction for the Leap Year.

Confused yet?

better but more..

also the year 2000 was one of those leap cycles- over 300 years for that to happen again

“New year” is just an arbitrary point in time anyway. When did time start? Why is a year calculated according to a random planet circling one of a trillion stars?

Time is just a variable in equations, with a unique property, that it like entropy can only increase.

According to the nuclear decay chart, everything will eventually become lead. Therefore decreasing entophy to zero.
