Length of the year of earth?

Answer 1

365/366 Days, 52 Weeks

Answer:

Since the Earth's orbit is not exactly in keeping with our days the year does not fall into an exact fit with our calendar. There are not an eact number of days or weeks in the year. There are several years in existence:

• The calendar year is either 365 or 366 days depending in the several rules for leap years.

• The Julian year is defined as exactly 365.25 days with one rule for leap years.

• The sidereal year (one revolution of Earths orbit about the sun) is 365.256 363 051 days (365 d 6 h 9 min 9.7676 s)

• The tropical year is 365.242 189 67 days (365 d 5 h 48 min 45 s)

• The anomalistic year is 365.259 635 864 days (365 d 6 h 13 min 52 s)
