Connecticut uses more than 183 days plus a permanent place of abode for people domiciled elsewhere, with an armed-forces qualification. Domicile and its exceptions are separate.
The rule
Domicile is a separate basis for residence, subject to applicable exceptions. This page tracks the presence route for people whose domicile is elsewhere. A day includes any part of a day, except transit through the state.
Counting the days
Counts recorded dates in Connecticut during the calendar year, including part days. US days recorded without a state are not counted.
- Choose the date through which you want to count, then add your recorded visits.
- Use the counting convention above. Identify the state for each US visit; nationwide US records are not assigned to a state automatically.
- Read the result alongside the conditions. Missing records and other eligibility requirements are not inferred from a total.
