Note : The Egyptians appear to have been the first to develop a solar calendar, using as a fix point the annual sunrise reappearance of the Dog star– Sirius, or Sothis in the eastern sky, which coincided with annual flooding of the River Nile. They constructed a calendar of 365 days, consisting of 12 months of 30 days each,  with 5 days added at the year’s end. The Egyptians failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into erro.

Note : In astronomy, an average astronomical unit is defined as the average distance from the Sun to the Earth,  or about 150m KM ( 93 million miles ). You can abbreviate astronomical unit as AU. Since the distance in astronomy are so vast, astronomers use this measurement to bring the size of numbers down.
For general reference, we can say that one astronomical unit (AU) represents the mean distance between the Earth and our sun. An AU is approximately 93 million miles (150 million km). It’s approximately 8 light-minutes. More exactly, one astronomical unit (AU) = 92,955,807 miles (149,597,871 km).
