Your school district is very unlikely to be here, as the preselected districts are current/former districts of the creator of this site. However, the custom countdown exists, and it may save in the future. A feature to add your own school districts for all users may be added in the future.

This is yet to be a feature. Only excluding weekends is supported.

If you have selected a date that has already happened, the countdown will begin to count up and will show negative numbers. This will be fixed soon.
