How many more sidereal months than synodic months will occur in one year?

Answer 1

Approximately 8,760 hours (365*24). In 2011, the mean tropical year was approximately 365 days, 5 hours, 48 minutes, 45 seconds, rather than 365 days, so the answer is slightly more than 8,765 hours.

Answer 2

In one year, there will be one more sidereal month than synodic months. This is because a sidereal month is the time it takes for the moon to complete one orbit around the Earth relative to the stars, while a synodic month is the time it takes for the moon to complete its phases (new moon to new moon).

Answer 3

Defining one "Earth Day" to be 24 hours, the earth's orbital revolution around the sun is

completed in 365.24 days (slightly rounded). This is the period referred to as one "year".

Answer 4

Well let's see . . .

A year is 365 or 366 days. That's 52 weeks plus 1 or 2 extra days.

For the 52 complete weeks, that right there is 260 week days, doesn't matter what day you start on.

The extra 1 or 2 days could be weekends or they could be weekdays. So . . .

The fewest weekdays a year can have is 260.

The most weekdays a year can have is 261 in an ordinary year, and 262 in a leap year.

Answer 5

A calendar as such doesn't have a certain number of days; a calendar is a way of organizing dates. A month has about 30 days, a year has about 365 days.

__________________________

There are three major types of calendars. They are solar, lunar, and luni-solar.

A solar calendar such as the commonly used Gregorian calendar (US, Europe, most "western" and Christian nations) is focused on keeping track of the days in one pass of the Earth around the Sun. This can be important because in pre-industrial agrarian societies, the calendar was how you knew when to plant your crops, and when to expect the rains to come. Because the year is not an exact number of days, intercalendary days need to be added every few years in order to keep the calendar in synch with the seasons.

A strictly lunar calendar keeps track of the phases of the Moon, without regard to the Sun. The Islamic calendar may be the most common lunar calendar. The New Moon marks the first of the month, and there are 12 months in the year. Note that a lunar calendar does not correct for the Sun; so in Islam, holidays like Eid al Fitr and Ramadan will occur in different seasons as the years go by.

A luni-solar calendar is primarily focused on the Moon, but corrects itself to keep the holidays in approximately the same seasons each year. The Hebrew calendar is luni-solar; Jewish holidays fluctuate in the Gregorian calendar, but the addition of "leap months" every few years keep Passover and Rosh Hashana in the spring and early fall respectively (in the northern hemisphere).

Answer 6

The Sun orbits within the Milky Way galaxy, and the galaxy moves with other galaxies within our portion of the universe. Everything is moving in multiple ways such that our solar system ends up between 9 to 11 billion miles (14 to 18 billion kilometers, 0.001 to 0.002 light years) away from where it was the year before.

Answer 7

A solar year, also called a tropical year, is a measure of the length of time it takes for the Sun to return to its original position as viewed from the Earth after the seasonal cycle. For example, the time between the Vernal Equinox of 2013 and the Vernal Equinox of 2014 was one solar year. It is almost 6 hours longer than the 365 day calendar year.

Answer 8

There are generally 365 days in a year, but on a leap year, it's 366 days in a year.

Actually no, there is 365.242199 to be exact, but a fraction i would say 365 1/4 days in a year.

Answer 9

The Sun doesn't rotate as a unit; the equator rotates in about 25 days but at the poles it's closer to 34 days.

Answer 10

365 days.

I suppose it's 365 days minus something, unless it's January first in a leap year.

What sort of question is that?
