How this is calculated

The Home Office doesn't check absences against a fixed calendar year — it checks every rolling 365-day window within your qualifying period. This tool takes every trip you enter and, for each one, works out the total absence within the 12 months ending on that trip's return date (plus the date you choose to check against), then reports the single worst window found.

Frequently asked questions

How many days can I be absent from the UK before applying for ILR?

No more than 180 days in any rolling 12-month period during your qualifying residence — checked as a rolling window, not a fixed calendar year.

Is the 180-day limit based on the calendar year?

No. You can be under 180 days in every calendar year and still breach the rule if a 12-month window spanning two calendar years contains more than 180 days absence — which is exactly what this calculator checks for.

What happens if I exceed 180 days in a rolling 12-month period?

Your continuous residence can be broken from the point the limit was reached, restarting your qualifying period — unless the Home Office exercises discretion for exceptional circumstances such as serious illness, bereavement, or a compulsory overseas work posting.
