Egyptian day Heru as King and Roman Regifugium? any differences?

Hello,

I found an antique Roman festival Regifugium
https://en.wikipedia.org/wiki/Regifugium

and antique Egyptian Festival of establishing Heru as King;The appearance before Ptah
e.g.: http://guardians.net/hawass/horus.htm

whether these events are random, and are also connected to each other?

Best regards
