Public-holiday data is taken from each country's official source. For Germany we use the consolidated Bundesländer lists maintained by the Bundesministerium des Innern and cross-check against each Landesregierung's published calendar; regional holidays such as Allerheiligen or Reformationstag are listed against the specific Land where they apply, not as nationwide holidays. For Austria we use the Arbeitsruhegesetz schedule plus the regional Landespatron days (Leopolditag in Niederösterreich, Florianitag in Oberösterreich and so on).

For France we use the Service-Public.fr official calendar with the Alsace-Moselle distinction explicitly noted. For Italy we use the official MEF list with separate notes for festività patronali at the municipal level (San Petronio in Bologna, Sant'Ambrogio in Milan, etc.). For Spain we use the Ministerio de Trabajo annual decree plus the autonomous community supplements and the municipal fiestas locales, which can vary from city to city.

For the Netherlands we use the Officiële Bekendmakingen and the CAO-bound observance notes (some employers observe Goede Vrijdag and Bevrijdingsdag, some do not). For the Nordics, Iberia and the Baltics we use the official ministerial or parliamentary publications, which we link in the source URL displayed on each country page.

Movable holidays — Easter, Pentecost, Ascension, Corpus Christi, Whit Monday, Orthodox Easter, Yom Kippur where observed, Eid al-Fitr where observed — are computed algorithmically using the standard ecclesiastical or astronomical rules, then cross-checked against the published date for the current year.

Working days for a country and period are computed as: all calendar days in the period, minus all Saturdays and Sundays (or the locally-defined weekend), minus all public holidays falling on a Monday-to-Friday that are observed in that country (or in the specific region selected). Bridge days are not subtracted unless the user has selected a bridge-day adjusted view.

We use the gregorian calendar throughout; ISO-week numbering follows ISO 8601 with Monday as the first day of the week. For half-day holidays (such as Heiliger Abend in some German collective agreements or Silvester in Austria) we treat the day as a full working day in the calculation and add an explanatory note rather than half-counting, because half-day handling depends on the employer's collective agreement.

Where a holiday falls on a Saturday or Sunday, most EU countries do not provide a substitute day, but a few do (the United Kingdom, Ireland and Portugal in some years). We follow the country-specific rule explicitly and flag the substitution where it applies.

Salary benchmarks combine three primary sources: Eurostat's Structure of Earnings Survey (the four-yearly SES release, plus annual updates of the indicator subset), each country's national statistical office (Destatis Verdienste, Statistik Austria Verdienststrukturerhebung, ISTAT Indagine sulla Struttura delle Retribuzioni, INSEE DADS/DSN, INE Encuesta de Estructura Salarial, CBS Loonstructuuronderzoek), and published collective-agreement schedules for sectors where these are binding.

We report median gross salaries by default because median is a more representative central tendency than mean in income distributions. Where the source publishes only the mean we say so explicitly and add the median when an external survey provides it. Senior, mid and junior bands are defined per the source's seniority classification (typically based on years of experience) — we do not invent a uniform classification across countries.

Cost-of-living adjustments use Eurostat's Comparative Price Levels indices for the relevant capital city or the country average where the city index is not published. Take-home pay calculations use the country's official tax brackets and social-security contribution rates for the year stated on the page; we do not interpolate to a partial year.

Each visa page cites the controlling primary legislation directly: Germany's AufenthG and BeschV; Austria's NAG, AuslBG and the annual Schlüsselkraft-Verordnung; the Netherlands' Vw 2000 and IND policy rules; France's CESEDA and the Talent Passport decrees; Italy's D.Lgs. 286/1998 and the Decreto Flussi; Spain's Ley 14/2013 and the Reglamento de Extranjería. The article or paragraph number is given inline next to the requirement it controls.

Salary thresholds (EU Blue Card minimum, RWR Card points, HSM salary minima, Talent Passport floor, HQP cap, etc.) are taken from the most recent official decree. For Germany the Blue Card threshold is the value published annually by the BMAS; for Austria the RWR Card thresholds are the values in the most recent Schlüsselkraft-Verordnung; for the Netherlands the IND publishes the HSM minima quarterly; for Italy the Decreto Flussi is published annually in Gazzetta Ufficiale.

Where a visa requires equivalent professional experience as a substitute for a university degree, we cite the implementing rule and explain how the equivalence is evaluated by the receiving country's authority — typically through ZAB Anabin (Germany), NARIC (UK), ENIC-NARIC (EU general) or the country's foreign-credentials office.

Processing times listed on visa pages are observed medians (not legal maxima) and are flagged as approximate. Where a country publishes official median processing times we link directly to the report.

Personal-income tax brackets are taken directly from each country's annual finance act or its implementing ordinance — Bundesfinanzministerium for Germany, BMF for Austria, Belastingdienst for the Netherlands, Service-Public.fr for France, Agenzia delle Entrate for Italy, Agencia Tributaria for Spain. Where the tax year does not run calendar-year (e.g. United Kingdom), we say so explicitly.

Social-security contribution rates and contribution ceilings (Beitragsbemessungsgrenze, plafond de la sécurité sociale, massimale contributivo) are taken from each country's social-insurance authority and republished annually.

VAT rules cite the relevant national VAT act plus the EU VAT Directive 2006/112/EC where the question is cross-border. Standard, reduced, super-reduced and zero rates are taken from the European Commission's TEDB (Taxes in Europe Database) and cross-checked against the national finance ministry's current rate sheet. Reverse-charge guidance for B2B cross-border invoicing follows Article 196 of the directive.

Annual data — holidays, tax brackets, salary thresholds — is refreshed in January of each year, usually within the first two working weeks. Mid-year changes (Germany's monthly BMAS adjustments, Austria's quarterly RWR threshold updates, country-specific mid-year decrees) are reflected within 14 days of the publication date and the page's "Last reviewed" date is updated.

Statistical data — average salaries, cost of living — is refreshed when the responsible statistical office publishes a new release, which is usually annual but occasionally semi-annual. We do not interpolate to fill gaps; we state the data year explicitly and re-publish when the new release arrives.

Known limitations: we currently do not cover collective-agreement-bound minimum wages at the sectoral level (CCNL in Italy, Mindestlöhne in Germany for specific industries, CBA wages in the Netherlands) — these are referenced in narrative form but not quantified on the salary pages. We also do not cover regional sub-municipal tax surcharges (German Kirchensteuer rate by Land, Spanish IRPF autonomic supplements, Italian addizionale comunale) at the page level; users with a specific need can email for the relevant rate.
