No, 4000 is a leap year. The rule is a year that is evenly divisible by 4 is a leap year, unless it is evenly divisible by 100, except if it is evenly divisible by 400. 4000 is divisible by 400. Just as 2000 was a leap year, but 2100 will not be.

It’s usually called the 4 - 100 - 400 rule. Of course, by 4000 we will be using the stardate calendar, anyway.

Your screenshot shows 29 days in February.

Actually, because the year 4000 AD is divisible by 400, it is a legitimate leap year.

I did search it up. I found no reputable reference that says that 4000 is not a leap year. The Wikipedia Leap Year article does not make 4000 a standard year. The CACM computer algorithm does not make it a standard year. So at best there is a difference of opinion. Let the people alive in 3996 (if there are any) deal with it.

As stated previously, that is not a rule for leap years.

No, being divisible by 4000 is not a rule. Being divisible by 400 is.

You really worried?

Good grief, are you serious with this??!! 4000 AD, in 2000 years time? I'm more worried about surviving the next 200 DAYS here in Europe!
