Made with leaflet, this map displays which coffee shops on the University of Maryland campus are open during the Fall and Spring semesters given a selected date and time. When the page initially loads it shows what coffee shops are currently open (assuming you are in the Eastern Standard time zone.)
I only added locations that are accessible to everyone, i.e., I did not include the dining halls, which have a prohibitive entry fee for those not on the meal plan. The time data was gathered using a web scraper script I wrote in Python. You can check it out here.

Note: This app works best in Chrome, Firefox, and Edge. If you are using Safari or Internet Explorer, enter your time in a 24 hour format with a leading zero. Be sure to include the colon as well (e.g. enter 8:30 AM as 08:30, enter 12:15 pm as 12:15).
