365

well except leap year where there is 366

A common year lasts 365 days. A leap year lasts 366 days. There are different types of year, however, the ones listed above are the standard measurements but there are others - http://en.wikipedia.org/wiki/Year#Variation_in_the_length_of_the_year_and_the_day

Earth takes about 365 and a quarter days to go round the sun, so that's how often the seasons and sun heights repeat. The spin of the earth defines the time and length of day. It turns 365 and a quarter times on the way round the sun. We can only jump the date by whole days, so we let the date get behind by a quarter of a day each year, and then catch up by adding in an extra one every four years. That's what a leap year is, catching up the missed quarter days with an extra day added to February. Of course, its not quite exactly a quarter, so we need an occasional extra day as things drift very gradually out by tiny bits, but I think it is only needed every few hundred years (care to Google it ?). Another whole topic is tiny variations in the spin rate of the earth, and rotation rate round the sun. Every now and then the international timekeeping systems add or subtract a second (as a result of astronomical checks), but they do it in the middle of the night, and you never notice.

365 1/4

364 and a half

365 days in a non leap year...366 in those years. It takes the earth just over 365 days to fully rotate around the sun, so every four years we add a year to the calendar to make up for the difference.

Well, first of all, that depends on what planet you’re on. Since we’re on Earth, though, I’ll assume that’s what you mean. Secondly, what kind of year are we talking about? Julian? sidereal? tropical? anomalistic? etc. Let’s assume, however, that your actual question is: How long does it take the Earth to complete a single revolution around the Sun? Let’s further assume that you’re looking for the mean answer to this question, since said answer will be slightly different, depending on your reference point. This would be a simplified definition of the “mean tropical year,” which is good enough for our purposes. Given the foregoing assumptions, one year is currently approximately 365 days, five hours, 48 minutes, and 45 seconds; or just under 365¼ days (which is why we usually have a leap year, every four years).

*chuckles* I have to admit I find it kind of ironic that your screen name is prodigy and you're asking such a basic question. 365, btw. Unless you're in a leap year, which makes it 366.

leep year or not.....earth or elsewhere in the solar system.....?

365 in a regular year and 366 in a leap year

365

Hold on, Im still counting... Se-ven-teee siiiix.....

Why was i not helpfull and get -1 look are lots of years..... =) 346.62 days — a draconitic year in some septenary calendars. 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. 365 days — a common year in many solar calendars. 365.24219 days — a mean tropical year near the year 2000. 365.2424 days — a vernal equinox year. 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. An average Gregorian year is 365.2425 days = 52.1775 weeks, 8,765.82 hours = 525,949.2 minutes = 31,556,952 seconds (mean solar, not SI). A common year is 365 days = 8,760 hours = 525,600 minutes = 31,536,000 seconds. A leap year is 366 days = 8,784 hours = 527,040 minutes = 31,622,400 seconds. The 400-year cycle of the Gregorian calendar has 146,097 days and hence exactly 20,871 weeks.

365.242199.... It's not really a whole number.

365 366 in a Leap Year which is every four years. The same year as the Olympics take place so the next Leap Year is 2012

365 duuuuuuuude.
