To get these events in your own calendar, copy this iCal URL and add it to your calendar app:

The process for doing this varies, but in the end you’re looking for a box you can paste a URL into (not something that asks you to upload a file). Look for words like “feed”, “sync”, or “subscribe”. If stuck, try a web search for your calendar app name plus “ical feed”.

Developer options To easily inspect the raw feed in your browser, replace .ics with .txt in the URL.

I’m Cora, a software engineer on the MBTA’s Customer Technology team. I created this project using the agency’s public data and APIs, partly as an exercise in learning Crystal, and partly as a tiny public service that fills a niche the MBTA itself does not.
