📅 TL.DateTimeExtensionsLibrary

Business-ready DateTime extensions for .NET: business day calculations, holiday evaluation, deadline handling, and fluent date arithmetic.
Extensões práticas de DateTime para .NET: cálculo de dias úteis, verificação de feriados, gestão de prazos e operações fluentes com datas.

O TL.DateTimeExtensionsLibrary oferece uma suíte de utilitários de alta performance para System.DateTime, simplificando cálculos de dias úteis em tempo constante $O(1)$, fatiamento temporal de intervalos (Chunks), limites de calendário e formatações especializadas com total preservação do DateTimeKind.

📦 Instalação

Adicione o pacote ao seu projeto através do .NET CLI:

dotnet add package TL.DateTimeExtensionsLibrary

🚀 Funcionalidades Principais

Dias Úteis, Feriados e Prazos

Método	Retorno	Descrição
`AddBusinessDays(days)`	`DateTime`	Adiciona dias úteis ignorando finais de semana com integridade de timezone.
`BusinessDaysBetween(endDate)`	`int`	Calcula o total de dias úteis em tempo constante $O(1)$ sem loops iterativos.
`BusinessDaysBetween(endDate, holidayProvider)`	`int`	Calcula dias úteis desconsiderando fins de semana e feriados providos via `IHolidayProvider`.
`BusinessDaysBetween(endDate, holidays)`	`int`	Calcula dias úteis desconsiderando fins de semana e a coleção de datas de feriados informada.
`BusinessDaysBetween(endDate, isHoliday)`	`int`	Calcula dias úteis desconsiderando fins de semana e datas que atendem ao predicado informado.
`BusinessDaysUntil(futureDate, ...)`	`int`	Sobrecargas para cálculo de dias úteis até a data futura considerando feriados ou provedor customizado.
`IsBusinessDay()`	`bool`	Retorna se a data atual corresponde a um dia útil (segunda a sexta).
`IsWeekend()`	`bool`	Verifica se a data corresponde a sábado ou domingo.
`NextBusinessDay()`	`DateTime`	Obtém o próximo dia útil subsequente.

Calendário e Particionamento de Intervalos

Método	Retorno	Descrição
`StartOfDay()` / `EndOfDay()`	`DateTime`	Retorna o primeiro (`00:00:00.000`) ou último (`23:59:59.999`) momento do dia com preservação de Kind.
`StartOfMonth()` / `EndOfMonth()`	`DateTime`	Retorna o início (`00:00:00.000`) ou fim (`23:59:59.999`) do mês com preservação de Kind.
`StartOfYear()` / `EndOfYear()`	`DateTime`	Retorna o primeiro instante do ano ou o encerramento em 31 de dezembro.
`StartOfWeek()` / `EndOfWeek()`	`DateTime`	Retorna o primeiro ou último momento da semana.
`Chunks(endDate, days)`	`IEnumerable<Tuple<DateTime, DateTime>>`	Divide intervalos longos em lotes menores para consultas paginadas e jobs em lote.
`CalculateAge()` / `Age()`	`int`	Calcula a idade exata com base na data de referência com ajuste bissexto.
`DaysUntil(target)`	`int`	Retorna a contagem de dias corridos até a data alvo.

Conversores e Formatações Especializadas

Método	Retorno	Descrição
`ToDateOnly()`	`DateOnly`	(.NET 8+) Converte diretamente para `DateOnly` preservando ano, mês e dia.
`ToTimeOnly()`	`TimeOnly`	(.NET 8+) Converte diretamente para `TimeOnly` preservando o componente horário.
`ToFriendlyDateString()`	`string`	Retorna texto humanizado (ex: "hoje", "ontem", "há 3 dias").
`ToISO8601()`	`string`	Converte para a representação universal padrão ISO 8601.
`ToOrdinalDateString()`	`string`	Converte para texto ordinal (ex: "1st", "2nd", "3rd").

💡 Exemplos de Uso

using System;
using DateTimeExtensionsLibrary;

public class ServicoPrazos
{
    public void ExecutarExemplos()
    {
        DateTime hoje = DateTime.UtcNow;

        DateTime inicioHoje = hoje.StartOfDay();
        DateTime fimHoje = hoje.EndOfDay();

#if NET8_0_OR_GREATER
        DateOnly apenasData = hoje.ToDateOnly();
        TimeOnly apenasHora = hoje.ToTimeOnly();
#endif

        DateTime vencimento = hoje.AddBusinessDays(10);
        int diasUteisRestantes = hoje.BusinessDaysBetween(vencimento);

        DateTime inicioAno = hoje.StartOfYear();
        DateTime fimAno = hoje.EndOfYear();

        foreach (var (inicio, fim) in inicioAno.Chunks(fimAno, 7))
        {
            Console.WriteLine($"Período: {inicio:yyyy-MM-dd} até {fim:yyyy-MM-dd}");
        }
    }
}
