## Text

In calculating any of the time periods identified in this code, the day of any act or service of notice is not included in calculating the deadlines. For example, if a student is served with an order on a Monday and the student has 10 calendar days to appeal the order, the date of service (Monday) does not count towards the time period, the next day (Tuesday) does count toward the time period, and the appeal would be due by 5:00 p.m. on the following Thursday.
If the last day of a time period ends on a Saturday or Sunday, the deadline is extended to 5:00 p.m. on Monday. If the last day of a time period ends on an EWU holiday, the deadline is extended to 5:00 p.m. on the next weekday following the holiday.
