Egypt is celebrating the beginning of the year 6262 today, Friday, according to the ancient Egyptian Calendar. The new year starts on the Feast of Neyrouz, the first day of the month of Thout, the first month of the Egyptian year.
The Egyptians also managed to pide the day into 24 hours, the time of the spring and autumn, and the days of the week.
The month may have been pided into four "weeks" of 7 or 8 days, reflecting each quarter of the lunar phases.
The difference between beginning the day at the first light of dawn or at sunrise accounts for an 11–14 year shift in dated observations of the lunar cycle.
It's thought that this calendar was invented by Thoth, the god of knowledge, the moon, measures, reading, and the alphabet. The first month of the Egyptian year's name is Thoth.
It's noteworthy that Egypt officially doesn't follow this calendar. However, it is still used in churches and by farmers.
It is also associated with local festivals such as the annual Flooding of the Nile and the ancient Spring festival Sham el-Nessim.
