Is it bad to keep my host machines to be on for like 3 months? With no down time?
What is the recommend? What do you do?

Never.
I had one Linux server that was up for over 500 days. It would have been up longer but I was organizing some cables and accidentally unplugged it.
Where I worked as a developer we had Sun Solaris servers as desktops to do my dev work on. I would just leave it on even during the weekends and vacations, it also had our backup webserver on it so we just let to run 100%. One day the sys admin said you may want to reboot your computer, it’s been over 600 days. 😆 I guess he didn’t have to reboot after patching all that time and I didn’t have any issues with it.
wait, they shut off? who knew.
Prod environments typically don’t have downtime. Save for patching every quarter that requires a host reboot.
Only when I swap or upgrade internal hardware.
These run 24/7/365.
If you need to reboot or shutdown regularly it’s not a server.
Only when children break into the server room.
Most things stay up 24/7
I have a couple machines I don’t currently use for anything so they’re powered off until needed.
Ideally I don’t.
Network services 24/7 (4 rpi3) Nas shutdowns every day at 23:30 and boots at 9:00, except we that boots at 10:00. Apci schedule management is embedded in firmware (qnap).
Servers shutdown at 23:15 and boots at 9:15 (we 10:15). For these rtcwake does the job.
WoL is enabled in case of.
If it is a Windows 95 server then every three days. Format and reinstall once every three months.
Everything in my lab is up 24/7 unless my UPS shuts it down in a power outage, if I’m doing any work inside the chassis or if I’m updating something. If you can handle the power bill, no real harm keeping it online all day.
Uptime is a score I need to beat!
Once a year for firmware updates. But my unraid box usually needs reboots once a month to stay stable.
