Tropical year, Time
The tropical year is the period of time for the ecliptic longitude of the Sun to increase by 360 degrees. The tropical year is often defined as the time between southern solstices, or between northward equinoxes. Because of the Earth's axial precession, this year is about 20 minutes shorter than the sidereal year. The mean tropical year is approximately 365 days, 5 hours, 48 minutes, 45 seconds (= 365.24219 days).List of all Tropical year to other time units individual converters.
