MDO has a similar academic calendar to Fairfax County Public Schools for teacher workdays, holidays, and breaks.  For information on our inclement weather policy click here.
 
Events can be added throughout the year and the calendar is subject to change.
If an event occurs on a non-school day for your child, you are welcome
to bring your child and stay with him/her for the event.
