In simple terms...

The added 5 days from 360 to 365 was the result of 'the great catastrophe' that occurred on might be more familiar with the term 'the biblical flood'. The event led to the earth's orbit to slighty widening.

The 'post-flood' Egyptians would have 5 days of mourning after this event (previously the cycle was approx. 360, like a circle)...and they obviously had to change their calendar...using the 'sothic cycle' (sirius).
