The "America 250 calendar" is a collection of events hosted by MANY fantastic partners in the area, plus there are a LOT of calendars online to choose from.

Thanks to Evan at Civic Lift, the NW Corner event calendars that they support now have a dedicated America 250 filter button at the top that shows events that have America 250 or A250 in the title or description. NOTE if America 250 is not in the title or description, it won't show when you click the America 250 filter button. 

Below are links to some of them. Each filters events based on the site's purpose. 

In addition to all that, there is a CT250 calendar here:  https://ctvisit.com/ct250
