Leap Year

No, because the system of leap years that we use now did not exist then. We did not start using the current system until 1752.

As of 2014, the next day Christmas will skip will be a Saturday.

The time it takes Earth to orbit the sun once is about 365.24219 days. Since that is not a whole number, in order to keep the seasons starting at the same times each year 24.219% of all years would have to have 366 days each while the other 75.781% has 365 days each. The way that was implemented was to make 97 out of every 400 years leap years by adding the 29th of February. A year is a leap year if it is evenly divisible by 4, like 2012 and 2016, unless it is also evenly divisible by 100, like 1900 and 2100. Then it is not a leap year, unless it is also evenly divisible by 400, like 2000 and 2400. Then it is a leap year. That system makes the average number of days per calendar year 365.2425.

The first leap year after 1996 was 2000. The first one after 2010 is 2012.

In a leap year, a day is added to February to keep the balance of the calendar making the year have 366 days in the year instead of 365. The number of days in all the other months stay the same which means that the months with 31 days stay the same. The months with 31 days are January, March, May, July, August, October, and December adding up to 7 months.

We have a leap year because it takes 365.25 days for the Earth to make one orbit of the sun. As we do not count quarter days in the calender, every 4 years we get 1 day so we add it to February and make it 29th of Feb a leap year.

That's the short answer. The longer answer is that it takes very slightly more than 365.25 days (365.256363004 days, an error of about 9 minutes a year) for the Earth to revolve around the Sun. Using the rule of every fourth year being a leap year, this adds up to an error of about 3 days (2.545 days) in 400 years, so the full rule is that every year evenly divisible by 4 is a leap year, except that century years not evenly divided by 400 are not leap years. Example, 2000 was a leap year, but 2100, 2200, and 2300 will not be leap years.

This system, the Gregorian Calendar, was put into place in 1582 by Pope Gregory XIII in order to correct for the prior Julian Calendar, which assumed 365.25 exactly. The change also included dropping the ten extra days that had accumulated, realigning the Vernal Equinox with March 21st, and it adjusted the Lunar Calendar as well, because it was off by about 4 days at that time.

It is interesting to note that these observations and calculation were made in the 16th century, using (by today's standards) not very accurate measurements. It is also interesting to note that England did not fully agree with this, due to the dichotomy between the Roman Catholic Church and the Church of England, so they kept the leap years for 1700, 1800, and 1900, stepping into alignment in 1923.

It takes about 365.2422 days for Earth to orbit the sun, but the number of days in a calendar year is always a whole number. In the Gregorian calendar, each regular year has 365 days and each leap year has 366 days. There are 97 leap years in every 400-year period. That makes the average length of a Gregorian calendar year 365.2425 days.

366 days in a year

a leap year

usually 4 years (2008-2012); sometimes 8 years (2096-2104)

Well, it would be more logical to celebrate it on March 1 since it's the day following February 28. But to be safe, just celebrate on both days like what I do :)

In cases of New Zealand citizens, the NZ Parliament has decreed that for a birthday that falls on February the 29, and is not a leap year, the legal birth date date shall be the preceding day, the 28th.

I was born on February 29th, and I celebrate my birthday on February 28th and March 1st, and every actual February 29th I have an especially big party.

No. St. Valentine's Day in 1997 was a day, not a year. 1997 itself was not a leap year.

Ignoring the hundreds years, leap years occur every 4th year, so this question is REALLY asking you:

Is 1918 divisible by 4?

Notice that 1900 / 100 = 19, and 100 / 4 = 25, so you only need to look at the 2 least significant digist: 18.

So I ask you this, is 18 divisible by 4? The answer to this is no.

So 1918 is not a leap year.

In solar calendars, like the Gregorian and Julian calendars, a leap year has one more day than a non-leap year (366 instead of 365).

Although leap years will never happen two years in a row, let alone 9, there would be 3294 days long, or 79056 hours. The equation is there's 366 days in a leap year multiplied by 9 years is 3294 days. And then 3294 days multiplied by 24 hours per day is 79056 hours.

Every leap year has at least 52 Wednesdays. The last leap year that started on a Wednesday was 1992. The last time February 29 fell on a Wednesday was 1984. The last leap year that ended on a Wednesday was 2008.

2nd july 183rd day is the mid point of year

there is how the heck should i know in a leap year

M=1000

cm=1000-100=900

x=10

ix=10-1=9

mcmxxix=(1000)+(1000-100)+(10)+(10)+(10-9)=1929

The probability that a year selected at random will be a leap year is 0.25.

At the time of answering this, in 2013, the next 3 leap years will be 2016, 2020 and 2024.

That was the year 1999.

February of course !

No.
