About ILRCAL

Look, I've tried the other ILR calculators. They're either missing half the rules, asking for data you don't have, or just plain wrong.

And don't even get me started on AI calculators.🤖ChatGPT thinks I was absent from the UK in 1723 and somehow managed to breach the 180-day rule by visiting my great-great-grandmother. Thanks, AI!

After one too many incorrect calculations that almost made me miss my ILR application window, I decided to just... build my own. Because apparently nobody else could read the actual UK government guidelines and do basic math.

What this tool does

Understanding UK ILR Absence Rules

This calculator helps UK visa applicants track their absence days for Indefinite Leave to Remain (ILR). Used by immigration lawyers, expatriates, and UK visa advisors to verify 180-day rule compliance and calculate continuous residence eligibility.

Key ILR Requirements: The UK Home Office requires applicants to demonstrate continuous residence. For the 5-year ILR route, you must not exceed 180 days absence in any rolling 12-month period, and total absences should remain under 450 days over 5 years. This calculator validates both these UK immigration rules.

Who Needs This: UK visa holders approaching settlement (ILR), British citizenship applicants, expats tracking residence requirements, and immigration solicitors preparing ILR applications. Ensure compliance before submitting your UK visa application to avoid refusals.
