You should check the Academic Calendar about a week before classes start. Make sure to make note of important dates such as begin and end dates, add/drop deadlines, last day to withdraw deadline and advanced registration dates.
Also check for dates that the College is closed (denoted here with the arrows).
Finally, check for dates that are unique for your needs. These may include Advising Week and Graduation Application deadlines.
You can access the Academic Calendars on the College Homepage in the bottom left corner or on your MyDaytonaState student portal.
