Any part of a day
Most states with a day test count any part of a calendar day you spend in the state as a full day. New York, Connecticut, Massachusetts, Minnesota and Pennsylvania say so in their rules. Fly from New York to Florida in the morning, and that day counts as a New York day and a Florida day.
Common exceptions
- Passing through. New York doesn't count days you're only traveling through the state to somewhere else, such as a connecting flight.
- Medical care. Some states, including New York, exclude days you're in the state for in-patient medical treatment.
- Short stays. Maryland counts a stay of 24 hours or less in a row as a single day.
- Contact periods. Ohio counts contact periods: parts of two days in a row with an overnight stay in Ohio.
- Keeping a home. Virginia and DC measure how long you keep a home in the state, not only days present.
Log it the safe way
When in doubt, log the day in every place you were. The tracker counts a day in two places for both, which is how most states will see it. Note the reason for unusual days, such as a layover or a hospital stay.
Prove it
A log is strongest with evidence: boarding passes, receipts, toll records and dated photos. What auditors ask for.
