Know your days before the border does.
One trip log, three rule engines. BorderDays tracks your Schengen 90/180, UK Statutory Residence Test and US substantial presence days — and warns you before a planned trip puts you over.
🇪🇺 Schengen 90/180
Rolling-window maths done right: entry and exit days both count. See days used, days left, and the exact date a planned trip would tip you over.
🇬🇧 UK SRT days
Midnight-rule day counts per tax year against your sufficient-ties threshold. Know when 45, 90 or 120 days is your real limit.
🇺🇸 Substantial presence
The 183 weighted-day formula (this year + ⅓ + ⅙) computed continuously, not in April when it's too late.
📄 Evidence export
One-click CSV of every trip and every count — the file your accountant actually asks for.
Built for contractors, expats, nomads and anyone whose freedom has a day limit.
