You can do the reverse unit conversion from tropical year to anomalistic year, or enter any two units below:
The anomalistic year is the time taken for the Earth to complete one revolution with respect to its apsides. The orbit of the Earth is elliptical; the extreme points, called apsides, are the perihelion, where the Earth is closest to the Sun (January 3 in 2011), and the aphelion, where the Earth is farthest from the Sun (July 4 in 2011). The anomalistic year is usually defined as the time between perihelion passages. Its average duration is 365.259636 days (365 d 6 h 13 min 52.6 s) (at the epoch J2011.0).
The mean tropical year is defined as the period of time for the mean ecliptic longitude of the Sun to increase by 360 degrees. Since the Sun's ecliptic longitude is measured with respect to the equinox, the tropical year comprises a complete cycle of the seasons; because of the biological and socio-economic importance of the seasons, the tropical year is the basis of most calendars.
The International Union of Pure and Applied Chemistry and the International Union of Geological Sciences have jointly recommended using defining the annus, with symbol a, as the length of the tropical year in the year 2000:
a = 31556925.445 seconds (approximately 365.24219265 ephemeris days)
We default to using the Gregorian year on this site, but you can select a specific type of year by entering the full name like "tropical year".
