24 hour boss limit

Alright -- so random question but i cant find the answer anywhere

When going to fight pap and zak i know you can only do it twice per day

but how is day defined --- is it a 24 hour period -- or does it reset like fame does at (im guessing) 12 at night

So basically if i do 2 runs at 6pm will i be able to do 2 runs at 6 am the next day (re: 12 hours later but a different "maple day") at either pap or zak

thanks in advance for the replies

24 hour period for pap/zak.
Example
1st Pap run- 12:00AM
2nd Pap run - 12:10AM
3rd Pap run can be anywhere from 12:00AM+

IF you do a run for something that you have to wait 24 hours to do again
oh and fame does not reset at midnight
Fame is 24 hours from the moment you do it
so say 5pm monday you can't fame anyone till atleast 5pm tuesday

IF you do a run for something that you have to wait 24 hours to do again

Actually, you can fame someone at 11:59pm and then someone else at 12:00 am O_o

Fame does reset at midnight.
