Notice: Office hour of [company Name] during [holiday name] holidays the offices will remain open from : am to : pm. [company name] will be closed on [date] and resume operations on [date].
I had a coworker once who hated it when she got somebody’s out of office message. I asked her why it got her so bent out of shape. “Because then I have to wait until they get back to send the message again!”

I wouldn’t be offended or consider saying anything to anyone who included this in their out of office message, but even as someone who is in a religion that forbids use of electronics on most holidays, I still think this message is 1) TMI; 2) doesn’t convey what it needs to convey unless you are explaining that you don’t use electronics during holidays, in which case you can just include that you won’t be checking email without including the religious explanation; 3) would come across to me as inclusion of personal information I don’t need, which would therefore strike an unprofessional tone,and I wouldn’t understand why you felt the need to include that info. How about “I’m out of the office without access to internet or email until (date). If you need assistance before this date, please contact…” Like I said, I think your colleagues are overreacting, but in general I would advise to leave all personal information out of your auto-reply — vacation, medical leave, religious observance, etc. — people do not need to know why you are out.
A. You should not. Office access will be restricted and operations limited to help reduce utility costs and other related expenses. Unless you are pre-approved by your department leadership to be on campus because your work cannot be interrupted by winter break – for instance, because you have research that would be adversely impacted – you should not be on campus during winter break. This break was established to promote health and well-being, so please take advantage of it.
