Why is 1700 is not a leap year.?

Question

Not only 1700.1300 is also not a leap year.

Answer 1

Leap years occur in years exactly divisible by four,
except that years ending in 00 are leap years
only if they are divisible by 400.

So, 1300, 1700, 1800, 1900, 2100, and 2200 are not leap years.
But 1600, 2000, and 2400 are leap years.

Answer 2

Leap year rules
In order to get a closer approximation, it was decided to have a leap day 97 years out of 400 rather than once every four years. This would be implemented by making a leap year every year divisible by 4 unless that year is divisible by 100. If it is divisible by 100 it would only be a leap year if that year was also divisible by 400. So, in the last millennium, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. In this millennium, 2100, 2200, 2300, 2500, 2600, 2700, 2900 and 3000 will not be leap years, but 2400 and 2800 will be. The years that are divisible by 100 but not 400 are known as "exceptional common years".

Answer 3

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by four, except for centennial years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not.

The reasoning behind this rule is as follows:

The Gregorian calendar is designed to keep the vernal equinox on or close to March 21, so that the date of Easter (celebrated on the Sunday after the 14th day of the Moon that falls on or after 21 March) remains correct with respect to the vernal equinox.
The vernal equinox year is currently about 365.242375 days long.

The Gregorian leap year rule gives an average year length of 365.2425 days.
This difference of a little over 0.0001 days means that in around 8,000 years, the calendar will be about one day behind where it should be. But in 8,000 years, the length of the vernal equinox year will have changed by an amount which can not be accurately predicted. Therefore, the current Gregorian calendar suffices for practical purposes.

SO... it was decided to have a leap day 97 years out of 400 rather than once every four years. This would be implemented by making a leap year every year divisible by 4 unless that year is divisible by 100. If it is divisible by 100 it would only be a leap year if that year was also divisible by 400. So, in the last millennium, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. In this millennium, 2100, 2200, 2300, 2500, 2600, 2700, 2900 and 3000 will not be leap years, but 2400 and 2800 will be.

The years that are divisible by 100 but not 400 are known as "exceptional common years". By this rule, the average number of days per year will be 365 + 1/4 - 1/100 + 1/400 = 365.2425.

Answer 4

Leap days are added to the calendar once every 4 years (29th Feb) but a greater accuracy is needed in order to keep the calendar in line. If every fourth year was a lep year then eventually the calendar would become several days out of synch so the turn of a century is not a leap year unless it';s divisible by 400.

1300, 1400, 1500, 1700, 1800, 1900, 2100 etc are not leap years. 1200, 1600, 2000 etc are leap years.

Answer 5

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by four, except for centennial years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not.

Answer 6

In order to keep the calendar in line with the seasons, slightly less than one day needs to be added every four years. The Gregorian calendar takes out 3 every 400 years. The rule is any year that is evenly divisible by 4, but not by 100, unless also divisible by 400.

1600 leap year
1700 not
1800 not
1900 not
2000 leap year
2100 not

Answer 7

hey everybody you have given correct answer for a year to be a leap year if it is divisible by 4 and century year should be divisible by 400.
but alas all of you including the person who asked did not realize that 1300 may or may not be a leap year.
do you know why?
because gregorian calendar starts from 1583 A.D. only after 1583 A.D the concept of leap year came. so remember 1300 A.D is in julian calendar may or may not be leap year.

Answer 8

yes it is because it is divisible by 4
and the rule states any year divisible by 4 is a leap year

Answer 9

Yes it is.
Comply.
