Nager.LongWeekend

Nager.LongWeekend is a lightweight, open-source .NET library that helps you calculate potential long weekends based on public holidays.
By providing a list of holidays and your defined weekend days, the library determines possible extended weekends — including those that can be created with optional bridge days.

✨ Features

• Detects long weekends based on given holiday data.
• Supports custom weekend definitions (not just Saturday/Sunday).
• Considers bridge days to extend weekends.
• Simple API with minimal dependencies.

📦 Installation

The package is available on NuGet

PM> install-package Nager.LongWeekend

🚀 Usage Examples

var holidays = new HolidayRecord[]
{
	new HolidayRecord

		Name = "Holiday Friday"
	},
	new HolidayRecord
	{
		Date = new DateOnly(2020, 01, 13),
		Name = "Holiday Monday"
	}
};

var weekendDays = new DayOfWeek[] { DayOfWeek.Saturday, DayOfWeek.Sunday };
var availableBridgeDays = 1;

var longWeekendCalculator = new LongWeekendCalculator(holidays, weekendDays);
var longWeekends = longWeekendCalculator.Calculate(availableBridgeDays);
