How many days can a Canadian stay in the US? Snowbird day counter
Heading south for another winter? Last winter's days follow you. Count your US trips across three years before you book the flight home.
Short answer: two different counts. A visitor is typically admitted for up to six months per visit (your I-94 date is what counts), and the US tax formula weighs your US days over three years against 183. This counter does the second.

Your winter, two different counts
Two counts, two different questions. The three-year formula counts US days for a tax test. Your visitor admission sets the date for your current stay. One does not replace the other.
A B-2 visitor admission is typically up to six months per admission. Check your I-94 admit-until date: that is the date that counts for your visit.
182 days is not a rule. A shorter winter can still bring the weighted total to 183 once the previous two years are included. Days at home in Canada do not reset it.
Provincial health-insurance limits are a separate question; this counter does not track them.
Form 8840 is for claiming the closer connection exception; see its instructions in Sources.
Example: Claire winters in Florida. Her trips are 5 Jan–20 Apr 2024, 15 Nov 2024–25 Apr 2025 and 20 Nov 2025–15 Apr 2026. On 8 Oct 2026, that is 105 US days this year, 157 last year and 154 the year before. The formula reaches exactly 183: 105 + 157 ÷ 3 + 154 ÷ 6.
Questions
How many days can a Canadian stay in the US?
For a B-2 visitor, a typical admission is up to six months per visit. Your I-94 admit-until date is what counts for that stay. Separately, the three-year tax formula adds your US days with different weights; this counter shows that total.
Is it 182 or 183 days?
182 days is not a universal rule. The tax formula reaches its threshold at 183 weighted days across three years, with at least 31 days this year. Your visitor admission has its own I-94 date.
Does a day trip count?
Yes. Driving across the border for the day uses one US day, even if you sleep in Canada that night. Arrival and departure days count too; overlap counts once.
What is Form 8840?
Form 8840 is for claiming the closer connection exception; see its instructions in Sources.
Do days in Canada between trips matter?
Those days add no US days. A break in Canada does not reset the three-year formula: your earlier US trips still carry their weight until their calendar year drops out.
Is anything I enter saved or sent?
No. The count runs in your browser. This page makes no network request with your dates and stores nothing; closing it clears them.
