Question

ancient egypt
hieroglyphics and cultural contributions
why did the egyptian year include a five day festival?
to make the calendar match the lunar cycle
to make the calendar match the days in a year
to make the egyptian and greek calendars match

Explanation:

The Egyptian civil calendar had 360 days (12 months of 30 days), but a solar year is about 365 days. The five - day festival was added to make the calendar match the actual number of days in a year. The lunar cycle is not the reason here, and there was no need to match Greek calendars at that time for this purpose.

Answer:

to make the calendar match the days in a year
