If Earth rotates around sun at 365.265 days a year, will seasons start earlier n 5,000 yrs

Drive Tesla will fix it

Isn't that why we have leap year?

How does this small discrepancy change seasons, day/night with actual rotations of earth around the sun actually taking 9 minutes longer than what our calendar year says.

From Weather Nation:


Leap years happen every 4 years, right?

Yes, but it's not that simple. We follow the Gregorian Calendar, which means leap years must follow three rules:

The year must be evenly divisible by 4

If the year can also be evenly divided by 100, it is not a leap year, unless ...

The year is also evenly divisible by 400. Then it is a leap year.

This means 2000 and 2040 are leap years, but 1800, 1900 2100, 2200, and 2300 are not.

Leap years are not a perfect system.

Because a year is 365.2422 days long and not exactly 265.25 days, the math doesn't always add up. We did the math ... we are rounding up and giving the calendar an extra 11 minutes every year, which doesn't seem like a lot, but that's a whole day every 130 years. As a result, certain leap years will be skipped, and those are the ones that are divisible by 100 but NOT by 400, which according to Smithsonian, "the next time a leap year will be skipped is the year 2100."


To the OP this was fixed remedied with the advent of the Gregorian Calendar.

In September of 1752, 11 days were taken out of the month correct the Julian calendar.

You can thank 2/29 for solving all your problems.

No because the governments of the world manipulate time on a micro scale in order to keep our seasons consistent.

They also account for procession of the poles which if left unaccounted for would eventually change our seasons to be the opposite.

Where we’re really screwed (and cannot be prepared for) is the eventual switching of earth’s magnetic poles.

Leap seconds are a thing. LINK

ETA: Or rather leap seconds are only a thing for a little while longer:

On 18 November 2022, the General Conference on Weights and Measures (CGPM) resolved to eliminate leap seconds by or before 2035. The difference between atomic and astronomical time will be allowed to grow to a larger value yet to be determined. A suggested possible future measure would be to let the discrepancy increase to a full minute, which would take 50 to 100 years, and then have the last minute of the day taking two minutes in a "kind of smear" with no discontinuity. The year 2035 for eliminating leap seconds was chosen considering Russia's request to extend the timeline to 2040, since, unlike the United States's global navigation satellite system, GPS, which does not adjust its time with leap seconds, Russia's system, GLONASS, does adjust its time with leap seconds.[6][7]

You are missing part of the “leap year” rules. You skip leap years every 100 years. Unless they are cleanly divisible by 400.

You don’t know about it because the last 100 year that we skipped was 1900 (the next is 2100). The year 2000 was a leap year because it is divisible by 400.

Wow that’s quite interesting
