Business/Holiday date handling [closed]

by

Nager.Date supports over 110 countries (US, DE, FR, RU, UK, …) the library is available for netstandard2.1. The full list of supported countries can be found here.

Update 2023

A new NuGet package is available. This means that the holidays are now queried by the WebApi and can be easily updated without having to update the NuGet package every time.

Nuget

PM> install-package Nager.Holiday

Example:

Get all publicHolidays of a year

using var holidayClient = new HolidayClient();
var holidays = await holidayClient.GetHolidaysAsync(2023, "de");

Check if a date a public holiday

using var holidayClient = new HolidayClient();
var holidays = await holidayClient.GetHolidaysAsync(checkDate.Year, "de");
if (holidays.Any(o => o.Date == checkDate))
{
    //Yes - New Year's Day
}
