How the count works
The ILR continuous residence absence count uses 180 whole days outside the UK in any 12 calendar months.
- The departure and return days are UK days. A same-day or next-day return counts as zero days away.
- The window starts the day after the date 12 months earlier. If that date doesn’t exist, use the last day of that month.
- Trips after the date you check are ignored. A trip returning later counts only through the date you check.
- Your highest window checks all the trips you enter. Days-back dates assume you don’t travel again; the limit date assumes you stay away.
For example, on 31 March the window starts on 1 April the previous year. On 29 February 2028 it starts on 1 March 2027.
Example: Sam checks 8 Oct 2026 after trips from 19 Dec 2025 to 4 Jan 2026, 2–13 Apr 2026 and 1–22 Aug 2026. Only the whole days between departure and return count: 45 days away, with 135 days left in the current window.
Questions
How do you count 180 days for ILR?
Start with the whole days you spent outside the UK in each rolling 12-month window. The day you leave and the day you return are UK days. This calculator shows your current count and the highest window in the trips you enter.
Is it 180 days per calendar year or any 12 months?
It is any rolling 12 months, measured in calendar months, rather than January to December. The window starts the day after the same date 12 months earlier, clamped to the last day of that month when needed.
Does the day I leave the UK count as an absence?
No — you count only whole days outside the UK. The departure and return days are UK days, so a Friday-to-Sunday trip counts as one day away.
Which routes use the 180-day rule?
Work routes and settlement as a partner or family use the 180-day count in any 12 months. Long residence uses it for absences starting on or after 11 April 2024. The EU Settlement Scheme counts months and is not covered here.
Is anything I enter saved or sent?
No. Your dates stay in this browser tab. They aren’t sent or saved, and closing the page clears them. Only your theme preference is saved.
Which absences can be excused?
Yes, some absences can be excused. The government’s guide in Sources explains the circumstances and records you’ll need.
