Office Schedule & Calendar

​One Schoolhouse is based in Washington D.C., and its office operates on Eastern Time.  The office is open from 9:00 a.m. to 4:00 p.m. ET each day.  Knowing that many of our students, schools, and families come from many time zones, we make every effort to answer calls after hours as well, though we ask for your patience and understanding if we cannot give you immediate help or information after hours.

The office is closed on most United States holidays, including the below dates.  If classes are running during these times, they remain active.
