Country Days Tracker for Tax Residency and Schengen 90/180

Many countries treat you as a tax resident if you are present there for 183 days or more within a defined 12-month period or tax year — though the exact test varies by country and can include other factors. Daytally keeps a per-country day count against your chosen tax-year boundary so you always know the number. It is a record-keeping tool, not tax advice; confirm the rules that apply to you with a professional.

The first problem is attribution: a travel day can plausibly belong to two countries, and rules typically hinge on where you were at a specific moment such as midnight. Daytally attributes each day to exactly one country using midnight in the local timezone, not UTC, and lets you override any day manually. That gives you a consistent, auditable count instead of a guess reconstructed from old boarding passes.

Visitors without a residence permit may stay in the Schengen area at most 90 days within any rolling 180-day window. The window is not a calendar quarter — it slides every day, which is why hand-counting goes wrong. Daytally computes days used, days remaining, and your earliest re-entry date for any date you pick, using deterministic date math tested against the official EU algorithm.

For any given day, you look back 180 days and count every day you were present in the Schengen area during that span; the total must not exceed 90. Because old days roll off the back of the window as new ones roll in, your remaining allowance changes daily. Daytally shows the full trace — which stays fall inside the current window and how they sum — so the calculation is never a black box.

You can re-enter once enough old days have rolled out of the trailing 180-day window to bring your count back under 90 — a date that is genuinely tricky to compute by hand. Daytally solves this inverse problem directly and shows your earliest legal re-entry date, plus the date your oldest days start rolling off.

Daytally does this with opt-in location visit monitoring: the device notices arrivals and departures in the background and writes country-day rows automatically, resolving the country on-device from an offline boundary table. Every auto-logged day remains visible and correctable, and the whole app also works fully manually with location off.

Not if it is built on visit monitoring rather than continuous GPS. Daytally uses the low-power visit and significant-location-change APIs, which let the system wake the app briefly at arrivals and departures instead of tracking your position all day. There is no always-on GPS involved.

Several major tax years do not — the UK year starts April 6 and the Australian year July 1, for example. Daytally makes the fiscal year a first-class setting per residency profile: pick a preset or a fully custom start date, and every 183-day counter and export rolls on that boundary instead of the calendar year.

What they need is a dated, per-country record they can check. Daytally exports the full ledger as CSV or PDF, generated on the device, with each day attributed to one country. Because the data lives locally and export is always available, your record can never be trapped inside an app you no longer use.

Yes — Daytally includes a plan-a-trip simulator. Enter a hypothetical stay and drag the exit date: the rolling window redraws live and flags the exact day the plan would exceed 90 days, along with the latest safe exit date. You find out at the planning stage, not at the border.

No, and honestly no app should. Residency determinations depend on more than day counts — ties, treaties, and country-specific tests all matter. Daytally gives you the accurate, auditable day record those determinations rest on, and leaves the judgment to you and your tax professional.

Daytally is local-first: the ledger, the day attribution, and the country lookup all live and run on your device, with no account and no server round-trip. Logging and calculations work offline, and your history cannot be wiped by a failed sync or a discontinued service — you can always export it.

The per-country ledger covers any rule that reduces to counting days present: tally the days in the country, watch the total, and export the record. The dedicated rolling-window calculator is built for Schengen's 90/180 rule specifically, which is the one travellers most often get wrong by hand.
