INDIAN HISTORY

Detailed explanation-1: -The Egyptian lunar calendar, the older of the two systems, consisted of twelve months whose duration differed according to the length of a full lunar cycle (normally 29 or 30 days).

Detailed explanation-2: -The ancient Egyptian calendar – a civil calendar – was a solar calendar with a 365-day year. The year consisted of three seasons of 120 days each, plus an intercalary month of five epagomenal days treated as outside of the year proper. Each season was divided into four months of 30 days.

Detailed explanation-3: -The Egyptian lunar calendar was not compatible with the lunar and solar years because the lunar calendar lost a day every four years.
