Definition of day unit: = 24 h = 1440 min. One day (solar day) is period of time from noon to noon = 24 hours. A solar day is the time it takes for the Earth to rotate about its axis so that the Sun appears in the same position in the sky. 24 [h] × 3600 [s] = 86.4 [ks] = 86400 [s]
Definition of year (Julian) unit: = 365.25 d average. The basic calendar year has 365 days, but in fact the Earth needs a little more time around the sun. The Julian calendar compensated this with leap year (every fourth year had 366 days). According to the formula, a Julian year has 365 + 1/4 = 365.25 days. But even with this compensation, the astronomical year slip 0.78 days every 100 years into real seasons. Therefore, most countries have moved to the Gregorian calendar introduced in 1582.
