Calculadora de Dias Úteis

The Business Days Calculator counts the number of working days between two dates by excluding weekends and public holidays from your chosen calendar. It supports thirteen built-in national holiday calendars, four workweek patterns (including the Sunday–Thursday Middle East schedule and 6-day or 7-day workweeks), custom company off-days, and half-day observances such as Christmas Eve afternoons. The result includes a calendar visualization, a month-by-month breakdown, and a list of every holiday that was excluded so you can audit the number quickly.

How to Use This Business Days Calculator

• Pick a start date and an end date, and decide whether the end date itself should be counted.
• Choose a workweek pattern — standard Monday–Friday, 6-day Monday–Saturday, Middle East Sunday–Thursday, or a 7-day open schedule.
• Marque um ou mais calendários de países para remover os feriados oficiais da contagem. Os botões rápidos Américas, Europa e APAC permitem selecionar regiões inteiras de uma só vez.
• Add custom holidays (such as company off-days or local observances) and half-day holidays, one entry per line in the format YYYY-MM-DD or YYYY-MM-DD: description.
• Clique em Calcular e confira o total de dias úteis, o detalhamento mensal, a lista de feriados e a visualização do calendário.

Working-Day Math

The calculator iterates one day at a time across the range. A date counts as a business day when it falls on a working weekday and is not present in any selected holiday calendar or in your custom full-day list. Half-day holidays still count as business days but reduce the effective working-day total by 0.5. If the same date appears in multiple sources (for example a country holiday plus a custom entry), the date is excluded only once and the source list reports both.

Holiday Calendars Covered

Os calendários integrados incluem Estados Unidos (federal), Reino Unido (Inglaterra e País de Gales), Canadá (federal), Austrália (nacional), Nova Zelândia, Alemanha (federal), França (nacional), Irlanda (público), Índia (gazetado central), Japão (nacional), China (continental), Hong Kong e Singapura. A calculadora aplica as regras de substituição de fim de semana para EUA, Reino Unido, Canadá, Austrália, Nova Zelândia e Irlanda — por exemplo, feriados dos EUA que caem no sábado são transferidos para sexta-feira, e os que caem no domingo são transferidos para segunda-feira. Os países com calendário lunar (China, Hong Kong, Singapura) usam as datas oficiais observadas publicadas pelo governo a cada ano.

Workweek Patterns

• Segunda a sexta-feira: a semana de trabalho padrão de cinco dias usada na maior parte do mundo para escritórios e serviços profissionais.
• Monday–Saturday: a six-day workweek common in retail, construction, and parts of Asia and Latin America.
• Sunday–Thursday: the Middle East schedule used in countries such as Saudi Arabia, the UAE, Kuwait, and Qatar, where Friday and Saturday are the weekend.
• All seven days: useful for 24/7 operations, healthcare rotations, or hospitality scheduling where weekends are working days.

Use Cases

• Project timelines and Gantt charts that need accurate working-day estimates.
• Payroll calculations where pay is based on actual workdays in a pay period.
• Prazos de envio e SLA que excluem finais de semana e feriados no país de destino.
• Legal contract deadlines where "business days" must be defined unambiguously.
• Planejamento de viagens e cobertura de ausência do escritório que precisam respeitar vários calendários nacionais ao mesmo tempo.

FAQ

Why do my results differ from another calculator? Most differences come from three things: whether the end date is included, which workweek pattern is used, and which holiday calendar is applied. Check those three settings before comparing tools.

Como os meios dias são contados? Um meio dia é um dia útil em que os funcionários folgam parte do dia. Ele ainda soma 1 à contagem de dias úteis, mas reduz o total efetivo de dias trabalhados em 0,5. A véspera de Natal e a véspera de Ano-Novo são exemplos comuns.

Os feriados religiosos e regionais estão incluídos? As listas integradas se concentram nos feriados oficiais nacionais. Feriados regionais (feriados estaduais dos EUA, dos Länder alemães, dos estados indianos, das nações do Reino Unido, etc.) e datas específicas de cada religião podem ser adicionados no campo de feriados personalizados.

Can I count weekends as working days? Yes. Switch the workweek pattern to Monday–Saturday or the 7-day schedule and the calculator will treat the weekend days as working days. Holidays that fall on those days will still be excluded.

How far ahead do the lunar calendars work? China, Hong Kong, and Singapore lunar-derived holidays are published year by year. The built-in tables cover the years where official dates have been announced, and you can paste additional dates into the custom holidays field for future years.
