About National Connecticut Day
National Connecticut Day is a creator-defined observance in National Day Calendar’s National State Days series, observed on August 10.
It is separate from Connecticut’s January 9, 1788 admission/statehood date and should not be presented as an official state-government holiday without separate legal authority.
Why National Connecticut Day matters
The day can be used to explore Connecticut’s communities, places, cultures and history while keeping the observance’s private creator-defined identity clear.
Connecticut state sources describe Native peoples including Pequot, Mohegan, Paugussett and Schaghticoke communities as having lived in the region for thousands of years and document continuing Tribal nations.
History of National Connecticut Day
National Day Calendar says it created the National State Days series in 2017, beginning with Delaware and moving through states in admission order with calendar exceptions.
The creator registry places National Connecticut Day on August 10.
Federal/state historical sources record Connecticut’s statehood on January 9, 1788.
The observance date and Connecticut’s statehood anniversary are therefore separate calendar identities.
