How long does it take for the admission office to respond to emails?

Usually other AOs ive contacted respond within 24 hours but its been a few days since i emailed my regional ao. Are they going to respond? Im not trying to be impatient im just geniuenly wondering

Brown winter break is 5 weeks long and goes until weds after MLK day

@iwannabe_Brown when I emailed my AO I got an automated response saying they’ll be back in the office on January 2nd?
