England has been using the Gregorian calendar since 1752. The Gregorian calendar averages 365.2425 days per 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).
The earth's orbital period is 365.23 days. Calendars are printed with 365 days in each year, plus one additional day every 4th year.
Well, different calendars have different prefaces / setups. but their are 365 days or sometimes 366. (only on leap years) in a year.
There are about 365.2422 days in a year.That's why every fourth year is a leap year unless it is divisible by 100, but it still is a leap year if divisible by 400.(So the year 2000 was the only even century leap year so far, the year 1600 was before this standard was adopted).There are many different definitions of a year so there are different lengths. some are listed below:346.62 days: a draconitic year.353, 354 or 355 days: the lengths of common years in some lunisolar calendars.354.37 days (12 lunar months): the average length of a year in lunar calendars, notably the Muslim calendar.365 days: a vague year and a common year in many solar calendars.365.24219 days: a mean tropical year (rounded to five decimal places) for the epoch 2000.365.2424 days: a vernal equinox year (rounded to four decimal places) for the epoch 2000.365.2425 days: the average length of a year in the Gregorian calendar.365.25 days: the average length of a year in the Julian calendar.365.2564 days: a sidereal year.366 days: a leap year in many solar calendars.383, 384 or 385 days: the lengths of leap years in some lunisolar calendars.383.9 days (13 lunar months): a leap year in some lunisolar calendars.365 1/4Note:having a leap year would only add one more day to the year.So in a Leap year it would be 236.Stricly speaking there a re 365 and a quarter, but we only have 365, then add up the quarters ever four years and have an extra day, making 366 days. Those are leap years and I think the next one is in 2008.
There are as many 'New Years' as there are calendars. Many of them totally different to the Gregorian calendar in general use. These calendars were introduced by various cultures to reflect their own way of counting the days and belief systems. No single person introduced the concept of new year.
Calendars include many things depending on where you get it from and how much it costs. The basic calendar will show the 12 months in the current year and will show the days of the week and their date. Other calendars will also show you celebrations world wide that are celebrated on that day. Other calendars have more holidays than others, just like others show the days beyond the current year you're in.
Throughout all of the 20th century, the Julian and Gregorian calendars differ by 13 days (March 14 Gregorian = March 1 Julian).

The period of revolution is called the "year", and equals about 365.2426 days.The Calendar and Leap YearsThe Earth takes approximately 365 days and six hours to revolve around the Sun. The extra six hours accumulate into an entire day every four years, so that a "leap year" will contain the extra 366th calendar day. The extra day is added as February 29 which only exists in a leap year.346.62 days: a draconitic year or ecliptic year is the time taken for the Sun (as seen from the Earth) to complete one revolution with respect to the same lunar node (a point where the Moon's orbit intersects the ecliptic)..353, 354 or 355 days: the lengths of common years in some lunisolar calendars.354.37 days (12 lunar months): the average length of a year in lunar calendars, notably the Muslim calendar.365 days: a vague year and a common year in many solar calendars = 8,760 hours = 525,600 minutes = 31,536,000 seconds.365.24219 days: a mean tropical year (rounded to five decimal places) for the epoch 2000.365.2424 days: a vernal equinox year (rounded to four decimal places) for the epoch 2000.365.2425 days: the average length of a year in the Gregorian calendar = 52.1775 weeks = 8,765.82 hours = 525,949.2 minutes = 31,556,952 seconds (mean solar, not SI)..365.25 days: the average length of a year in the Julian calendar.365.2564 days: a sidereal year.366 days: a leap year in many solar calendars = 8,784 hours = 527,040 minutes = 31,622,400 seconds.383, 384 or 385 days: the lengths of leap years in some lunisolar calendars.383.9 days (13 lunar months): a leap year in some lunisolar calendars.http://wiki.answers.com/How_long_does_it_take_for_the_Earth_to_revolve_around_the_Sun#ixzz1KSMrZDxe

There are many calendars, none started at the same time.
