## Current revision

The interval required for the earth to complete one revolution around the sun.

A sidereal year, which is the time it take for the earth to make one absolute revolution around the sun, is 365 days, 6 hours, 9 minutes, and 9.5 seconds. The calendar year begins at 12 o'clock midnight local time on the night of December 31st-January 1st. Currently, the Gregorian calendar of 365 days is used, with 366 days every four years, a leap year.

The tropical year, also called the mean solar year, is dependent on the **seasons**. It is the interval between two consecutive returns of the sun to the vernal equinox. In 1900, that took 365 days, 5 hours, 48 **minutes**, and 46 **seconds**, and it is decreasing at the rate of **0.53** second per century.

One year is ~365 days x 24 hours x 60 minutes x 60 seconds = **31,536,000** **seconds**.
