Leap Year

Light travels at 300,000 km/sec or 3*10^8 m/s. Thus 1 light second= 3*10^8 m 1 light minute=1.8*10^10 m, or 18 billion meters, (18 gigameters), 18 million km, 11.1 million miles The Sun is 8.4 light minutes from earth. 1 light hour= 1.08*10^12 m, 1.08 trillion meters, (1.08 terameters) 1.08 billion kilometers, 667 million miles 1 light day=2.59*10^13 m, 25.9 terameters, 25.9 billion km, 16 billion miles 1 light year= 9.47*10^15 m, 9.46 petameters, 9,460 terameters, 9.46 trillion km, 5.84 trillion miles. The nearest star is Alpha Proximi, 4 light years away or 23.4 trillion miles from earth. If you could drive there at 60 mph it would take 4.45*10^7 years, 44.5 million years The fastest humans were the Apollo astronaughts, who reached 25,000 mph, it would take them 106,849 years to get Alpha Proximi. 1 parsec is 3.27 light years, =3.1*10^16 m, 31 petameters, 310 trillion km, 191.35 trillion miles. The nearest possible earth like planet, Gliese 581 C, is 20.5 light years, or 6.3 parsecs away. Useing today's conventional chemical rockets, (25,000 mph) it would take 547,198 years to get there. Using fusion rockets that can achieve speeds of .5c (50% the speed of light) it would take 41 years as viewed from earth, (at such relativstic speeds time would slow down for anyone inside the rocket, so it would seem as if 35.5 years had passed). At .75c the trip to Gliese 581 C would take 27.3 years as seen from earth, 18.1 years elapsed inside the rocket. At .9c (the realistic limit for even the most advanced antimatter powered space ships due to the exponentially larger energy requirements needed to speed up as you approach the speed of light) the trip would take 22.8 years as seen from earth, for those inside the ship 9.9 years would have passed. Thus it is clear that only 4 possibilities exist for humans reaching other earth like planets, (10 years away is the closest possible earth like planet, most others will be centuries or millenia away) 1. Discover how to travel faster than light by warping space, theoretically possible but the energy requirements are too great for this to be practical, most likely faster than light travel is impossible. 2. Advance medicine to the point where we can slow or stop aging and give humans life spans measured in centuries of millenia. 3. Develop a way to put humans in suspended animation. 4. Build generational ships where several generations of people are born, work and die, while in transit. Also note that due to time dilation effects, (time slows down as you travel at higher velocities) at .9c velocity for each 1 year that passes on the ship 2.33 years passes on earth. So interstellar empires are impossible, since it would take decades or centuries to communicate with other planets, and even visiting earth from Gliese would mean arriving decades into the future, from the perspective of someone onboard a ship coming to earth. Thus any colonists leaving earth would almost certainly be making a 1 way trip.

Including 2000, there are 243 leap years from 2000 through 3000.

Most centuries have 24 leap years, every four years from the fourth through the 96th year of the century. Only once every four centuries is the last year of the century also a leap year (like the year 2000).

You can contact the manufacturer and give them the serial number, or you can check in a reference guide, such as the Blue Book of Gun Values. Some information is listed in the back of the book.

There are four weeks and a day in February!!

2017 is not a leap year because it does not follow any of the rules to be a leap year, like being divisible by 4. The reason it starts 2 days later than 2016, is that the extra day that is skipped in a leap year only starts from the 1st of March, because the extra day is the 29th of February, and then follows into the months of January and February of the following year.

Not every date in a leap year skips a day, just ones from after the 29th of February. It is the dates in January and February of the following year that have skipped a day, and once you get to the 1st of March in the year after a leap year, you are back to being one day ahead again. The skipped day is not from the 1st of January to the 31st of December in a leap year, but from the 1st of March in a leap year to the 28th of February in the following year.

2016 is a leap year, but the 1st of January 2016, is not two weekdays after the 1st of January 2015, because the leap day has not happened at that point. So it isn't until the 1st of January 2017, that the day will have been skipped. So that is why the 1st of January 2017 is 2 weekdays later than the 1st of January 2016.

Because that's the way it has been defined. The distribution of leap years was defined so that the average length of the calendar year (365.2425 days) was as close as possible to the real length of the year (about 365.2422 days).

The most recent leap year was 2008. The next ones are 2012 and 2016.

366

The odds are 91% that any given 12-year period will include three leap years. The other 9% of the time there are two leap years in a 12-year period. There are never four leap years in a 12-year period.

A Steelcase Leap Chair costs about 869.99 U.S. dollars. The prices will range depending on the location where the purchase is made. It would be ideal to look around for the best deal.

It was in 1752.
1948

Yes it can. It last happened in 2004 and will next happen in 2032.

Well, you have a leap year every 4 years. so the next leap year will be in 2012, 2018, 2022, 2026, 2030 and so on...

There were 49, remembering that 1800 and 1900 were not leap years. They were: 1776, 1780, 1784, 1788, 1792, 1796, 1804, 1808, 1812, 1816, 1820, 1824, 1828, 1832, 1836, 1840, 1844, 1848, 1852, 1856, 1860, 1864, 1868, 1872, 1876, 1880, 1884, 1888, 1892, 1896, 1904, 1908, 1912, 1916, 1920, 1924, 1928, 1932, 1936, 1940, 1944, 1948, 1952, 1956, 1960, 1964, 1968, 1972 and 1976.

2 years and 69 days

There is no year 0 in our calendar; 1 B.C. is a leap year.

The day after the 124th day of the year.

A leap year is 366 days long so it does not fall on a single day of the week. All 7 days of the week will regularly occur during a leap year. The leap day itself, which is probably what you meant, will occur on Monday, as the 29th of February 1916, the next leap day, is a Monday.

2016 is the next leap year. In 2016 there will be 52 Wednesdays. There will be 5 Wednesdays in the months of March, June, August and November. If you mean when will the next February in a leap year with 5 Wednesdays be, that will be in 2040.

the year when India got independence is on 1947 if you divide the year by 4 and the qoutient is 0 the year is a leap year

Winchester did not serialize the model 69,69A.I can say that the model 69A was made during the years 1935-1963,with a total production of 355,000.
