Kept by Skyler Bissell. Last correction logged August 13, 2026.
Every number on this site carries a source and a date. When one of them turns out to be wrong, it gets fixed and the fix gets written down here, with the value before, the value after, and the source that settled it.
I publish this for a plain reason. Anyone can claim their data is careful. The only way to show it is to say what you got wrong, in public, with a link that lets someone check.
Corrections to a published value, where the number itself moved or the thing it measured turned out to be different from what we thought. 16 of them so far.
Routine refreshes are not here. A tax bracket moving with a new tax year is maintenance, and listing it would bury the entries that matter.
Most of them are one of two shapes, and the second is the dangerous one.
The first is a stale value. A law changes, a price moves, and the stored number quietly stops being true. Those are easy once you look.
The second is a unit error, where the number is copied correctly and means something other than what we assumed. Norway grants 25 vacation days, and it is right there in the statute, but the statute counts a six-day week, so it is 21 in the terms anyone reading our site would expect. Sweden also says 25 and is correct, because Swedish law excludes Saturday. The headline number cannot tell you which is which. Only the definitions section can, and it is the kind of mistake that survives every sanity check, because the value matches the source exactly.
That is why several entries below arrive in batches. Once a unit error turns up in one country, the honest response is to ask the same question of every other country rather than fix the one that got reported.
Readers flag numbers that look wrong, straight from the calculator, and those reports do real work. The Vienna entry below exists because someone told us we had left out most of the Austrian parental leave entitlement, and they were right. Every report gets a decision, including the ones we end up rejecting.
The rest come from audits that take one field and sweep it across every country at once. That is a slower way to work and it finds the errors nobody would ever report, because a number can be wrong in a way that still looks completely reasonable.

New York City neighborhood rent multipliers: was All-unit borough ratios, now Bedroom-matched ratios. Corrected August 13, 2026.
The borough multipliers were built from an all-unit average and then applied to a per-bedroom median, so two different baskets were being multiplied together. Both halves of the ratio now come from the same publisher, the same table, the same month and the same bedroom count.
17 countries social insurance base: was Charged on income after a pension deduction, now Charged on gross earnings. Corrected August 13, 2026.
Most statutes levy the employee share of social insurance on gross pay, so a voluntary private pension contribution should not shrink it. Seventeen country branches were letting it, which quietly understated the charge. The Netherlands was checked and left alone, because Dutch law does reduce the base and the branch was already right.
All countries pre-tax retirement deduction: was Uncapped everywhere, now Capped to each country's statutory ceiling. Corrected August 11, 2026.
The engine granted an unlimited pre-tax retirement deduction in every country, including ones whose law grants no such relief at all. Every city now carries a sourced ceiling.
Norway statutory vacation days: was 25 days, now 21 days. Corrected August 8, 2026.
Ferieloven grants 25 virkedager and defines the unit in the same paragraph as every day that is not a Sunday or a public holiday, so Saturday counts and the week is six days long. In five-day terms that is 21. The familiar Norwegian five weeks comes from collective agreements rather than the statute.
United Kingdom statutory vacation days: was 25 days plus 8 bank holidays, now 20 days plus 8 bank holidays. Corrected August 8, 2026.
The UK floor is 28 days in total, and an employer may count the bank holidays inside it. We were adding the bank holidays on top of a figure that already included them, which overstated paid time off by five days.
United Arab Emirates statutory vacation days: was 30 days, now 22 days. Corrected August 8, 2026.
Article 29 grants 30 days, and the government's own guidance says public holidays falling inside the leave are counted as part of it, which makes the figure a calendar span. We had stored it as though it were working days.
Kazakhstan statutory vacation days: was 24 days, now 17 days. Corrected August 8, 2026.
Article 88 grants twenty-four calendar days in as many words. Taken as a block that spans three weeks and three days, which is 17 working days.
Singapore statutory vacation days: was 14 days, now 7 days. Corrected August 8, 2026.
The Employment Act sets 7 days in the first year, rising one day a year to a ceiling of 14. We had stored the ceiling as if it were the floor. This field records the year-one legal minimum.
Hong Kong statutory vacation days: was 10 days, now 7 days. Corrected August 8, 2026.
The Employment Ordinance gives 7 days in years one and two, laddering to 14 at nine years of service. The stored 10 was a mid-ladder rung rather than the entry point.
Canada statutory vacation days: was 15 days, now 10 days. Corrected August 8, 2026.
Two weeks after twelve months is the floor in every province we cover and in the federal code. Fifteen days is the three-week tier, which arrives at year five in most of them.
Ireland statutory vacation days: was 22 days, now 20 days. Corrected August 8, 2026.
The Act sets the entitlement at four working weeks and defines a working week as the number of days the employee usually works. On the five-day week we model, that is 20.
Egypt statutory vacation days: was 21 days, now 15 days. Corrected August 8, 2026.
The governing law changed underneath the value. Labour Law 14 of 2025 repealed the 2003 Act in full from September 2025 and sets 15 days in the first year, with 21 only from the second.
Denmark public holidays: was 11 days, now 10 days. Corrected August 8, 2026.
Store Bededag stopped being a public holiday in January 2024, with affected employees compensated by a salary supplement instead. Our count still included it.
Berlin median asking rent: was 880 / 1,231 / 1,650 / 2,500 EUR, now 670 / 940 / 1,330 / 1,850 EUR. Corrected August 7, 2026.
The old ladder came from a real-estate blog aggregate and priced every bedroom count above the market, getting worse with each bedroom. Rebuilt on the city investment bank's own market report, which reads about 40,000 listings.
Vienna paid parental leave: was Maternity protection only, now 73 weeks including childcare benefit. Corrected August 7, 2026.
A reader pointed out that we had captured Mutterschutz and left out Kinderbetreuungsgeld entirely, which is most of the Austrian entitlement. They were right. The same shape turned up in Poland and Estonia when we went looking, and both were fixed too.
Bundeskanzleramt, einkommensabhaengiges Kinderbetreuungsgeld
Germany income tax: was Flat 33.5% band, now Section 32a tariff. Corrected July 31, 2026.
Two faults stacked. The bracket was a flat band standing in for a continuous formula, and the standard deduction sat at zero, so the ladder ran on gross income. A reader's own payslip showed 9,410 EUR where we had been printing 14,628.
Shipped corrections to a published value: what the number was, what it is now, why it moved, and the primary source that settled it. Routine annual refreshes are not listed, because a bracket moving with a new tax year is maintenance rather than a correction.
Three ways. Readers flag numbers that look wrong from the calculator itself. Audits sweep one field across every country at once, which is how unit errors surface. And a correction in one place often implies a check somewhere else, so fixes tend to arrive in groups.
Yes. Every entry links the primary source, usually the statute or the statistics office, so the underlying fact can be checked without taking our word for it.
Open any comparison, go to the Breakdown, and use the flag beside the row. It takes a number and no account. If it holds up against the source, it gets fixed and it lands on this page.
