Is a cosmic year the same as a leap year?
A cosmic year is 220 million years, the time it takes for the entire Milky Way galaxy to rotate once.
If by a cosmic year you mean a sidereal year, the answer is still no. A sidereal year is the time it takes the Earth to go completely around the sun, which is 365 days, 6 hours, 9 minutes, and 9.54 seconds.
The difference between the calendar year and the sidereal year (approximately 6 hours, or a quarter of a day) is the reason we add a leap day to the calendar every four years. And the leftover amount (the extra 9-plus minutes) is the reason we subtract a leap day from three out of every four century years (years ending in '00', such as 2100).

No. 2000 was a leap year. Only 2016 and 2020 are leap years during that period and neither of them are the same as 2000 was. 2024 is also a leap year, but is not the same as 2000. 2028 will be the same. Read More

Yes, if the year is divisible by 4 then it is a leap year with this exception: A century year (year ending in 00) is only a leap year if it is divisible by 400 So the years 1800, 1900, 3000 are not leap years, for example, but the year 1600, 2000 were leap years and the year 2400 will also be a leap year, if we are still using the same calendar then.

A second is 1/604800 of a week, so a year with a leap second has an extra 1/604800 week - this is small enough that it makes very little difference to a whole number, thus a year with a leap second has effectively the same number of weeks as a year without a leap second: 52 weeks plus one (or two if it is a leap year) day(s).

Yes, 1804 was a leap year. Any year whose number is evenly divisible by four is a leap year, with two exceptions. Any year whose number is evenly divisible by 100 is NOT a leap year. Any year evenly divisible by 400 IS a leap year. So, 1800 was not a leap year, while 1804 WAS a leap year. 1900 was not a leap year, while 2000 (being divisible by 400) was a leap year. Read More
