Both the calendar and universal keycard access were elements of Gusmorino's and Vice-President Sujean S. Lee '03's campaign platform.
The only other bill on last night's council agenda called for a $20 allocation to institute a "Valentine's Datamatch," a website run by the Harvard Computer Society that tries to match students romantically based on their responses to a series of questions.
