What PDC ? are you running an NT4-style DC as well ?
No I thought not, it is just your first DC and just because it is your
first DC doesn't mean it holds any FSMO roles.
Will the person who decided that calling the first DC a 'PDC' was a
good idea, please identify themselves, I could then explain to them why
calling it a 'PDC' is a stupid idea ;-)

An AD DC really needs to be on 24/7, but it can probably handle being
off for a short while, replication should fix any changes. Being off
for a number of days is a different thing, what if numerous changes
have been done on other DCs, these may clog up your network whilst
they are replicated. There is always the possibility that the
replication could go the wrong way and new entries could be removed on
the other DCs, this is unlikely, but possible.
If you plan on turning off a DC for a long time, you should also plan
to demote it before you turn it off.
