Common misconception: 450 days, not 540
Some sources, including older immigration handbooks and forum threads, state the absence cap as 540 days. The statutory figure under BNA 1981 Schedule 1 ¶5(2) is 450 days across a 5-year qualifying period. The 540 figure appears to conflate the BNA cap with unrelated long-residence rules. The number to track against is 450.

Frequently asked questions
The day-count rule is set by BNA 1981 Schedule 1 paragraph 5(2): a maximum of 450 days of absence over the 5-year qualifying residence period.
The statutory figure is 450 days. The 540 figure that circulates online appears to conflate unrelated long-residence rules with the BNA cap. The number to track against BNA 1981 is 450.
The BNA 1981 sets the citizenship-by-residence framework for British Overseas Territories citizens. Cayman's Immigration (Transition) Act (2022 Revision) section 28(3) — as amended in 2025 — governs how presence in Cayman is recorded for that purpose.
The statutes define an absence at the level of a whole day spent outside the territory. This calculator follows that whole-day rule. Partial days are not split.
