What is a Rolling 12-Month Period?
A rolling 12-month period means any consecutive 365-day window, not just calendar years. For UK immigration compliance (like the 180-day rule for continuous residence), authorities can check any 12-month period within your assessment timeframe.
Example:
If you were absent for 100 days from January 1 to April 10, and then 90 days from November 15 to February 13 the following year, the period from November 15 (Year 1) to November 14 (Year 2) would contain 190 days of absence, exceeding the 180-day limit.
This calculator checks every possible rolling 12-month window in your selected timeframe to find the maximum absence period, ensuring you don't miss any problematic windows.
