Constitution Day
Institutions receive federal funding are required to post and acknowledge the September 17, 1787, the day of the signing of the United States Constitution. Educational programs celebrating this commemoration will be posted through internal College channels.
Religious Observances
Massachusetts state law regarding student absence due to religious beliefs has been adopted by Olin College as follows: “Any student who is unable to attend classes or participate in any examination, study, or work requirement on a particular day because of his or her religious beliefs is excused from any such activity. The student will be given the opportunity to make up the work that was missed, provided that the makeup work does not create an unreasonable burden upon the college. The college will not level fees or charges of any kind when allowing the student to make up missed work. In addition, no adverse or prejudicial effects will result because students have made use of these provisions.”
The online interfaith calendar is commonly used by community members to identify dates for specific religious observances each year.
