When do you turn off the tubes?

Having had recent surgery and spending a lot of time at home, I was wondering how long a break from music do you feel you need to be taking before turning off your tube amplifier.I could leave it on all day even when not listening but that would be 12+hours/day.While my PrimaLuna Dialogue HP is gentle on tubes, the thought of retubing 8 KT150s is an expensive prospect.I usually turn the amplifier off if I am not going to listen for around 3 hours.What do other people do?

I have new tubes I want to burn them in, what is the longest to leave them playing at a time?? How many hours should I burn them in??
woo Audio had an interesting answer, “don’t worry about it, and each time you listen to music it will sound better!

On for 15, prior to listening, then off when done.

I have a tube DAC and a tube pre both with some expensive NOS tubes.  Those components go on for 10 minutes prior and off when I'm done listening......or when my girl gets frisky.  Damn NOS is expensive.

My preamp and single ended amp both use 6SN7GTBs and my preferred NOS RCAs and Sylvania "chrome domes" aren't expensive at all (relatively). A NOS Amperex was supplied with my Dennis Had power amp and still sounds great after a couple of years. You can, of course, spend a lot on certain brands, but I won't.
