Another way to see this difference is to notice that, relative to the stars, the Sun appears to move around Earth once per year. Therefore, there is one fewer solar day per year than there are sidereal days.
The sidereal year (to complete an orbit back to where the earth started) is approx 365.2564 days or 365 days, 6 hours, 9 minutes, 13 seconds. Our calendar is based on the tropical year so that the seasons stay in the same place.365 days, 5 hours, 46 min, & 48 sec.t takes approximately 365.25 earth days of 24 hours each to complete one orbit around the Sun. On calendars, we just state 365 days, and make up for the 0.25 days as an ext â¦ ra day every four years. This is called the 'leap year', where we have 366 days instead of 365, with an extra day in February. Don Dfoofnik.
