I'm using the built in connector for the calendar.csv dataset. I noticed this only goes back to 2010. Is there one available that goes back further?
I assume you're meaning the calendar.csv that is available in the Domo Stats Dataset. If this is the calendar you're referring to, it will only go back to 2010.
If you want a calendar that spans a larger range, you can upload your own calendar using the file upload connector. Another great alternative is always the Google Calendar Connector.
