A day when a part of seniors, especially the ones that don't have AP or honor classes, don't go to school which causes the school a big financial damage since it doesn't receive government's money for 2/3 the class yet has to pay the same amount for teachers, subs, utilities, etc.
Senior ditch day is often agreed among some students to pick some days that are special.
In my school, senior ditch days are days when the day and month added will be 9, like 2/7, 5/4, or 12/6
