A quick question on Planetary Hours and charts.

So Q1:

Does anyone use Modern Planets for doing Planetary Hours? If so could you let us know what system you use? Like we know Saturn, Venus, and Mercury, can be switched out on Days do to the day having two rulers.

But the same doesn't exactly translate to Hours well XD.

Q2:

Is there such thing as an Astrology chart that'll show when all the planets will be interacting and how instead of manually plugging in dates on a chart to take a look?

I myself have not tried to use modern planets to modify the well-established planetary hour systems.
