Planetary days/planetary hours

So i've been doing some studying and ive come to understand that tuesday is the real friday. Just gonna a link below

https://glorian.org/books/practical-astrology/the-zodiacal-course/capricorn

in this link, it says this 'In this manner, the twelve hours of the day are divided into four parts, each of them lasting three hours.'

I understand that tuesday (being the real friday) starts off under the rule of venus. so 0am to 3am = venus time. The author states that the 12 hours of the day are ruled by 4 planets only. So 3am-6am follows the next planet on the list, the sun. Is this correct? on and on it goes for 2 more planets until it reaches 12pm or noon.

0am-3am on modern day tuesday = venus time? And so if you want to work with the energy of venus, you're gonna want to aim for this time on a tuesday. 0am-3am.

This is all with respect to your local time zone, right?

and one side question, i dont find in this link what the planetary hours for 12pm-12am is. 4 planets, 3 hours each only accounts for half of the day. please clarify. Samael aun weor did say that each day is ruled by only 4 planets for 3 hours each so after 12pm there'd be no planetary influence?? i hope you understand me and thanks in advance
